10 coins -6 coins = $1, so the coins are 1/4 dollars, ie. Quarters
As others have noted, John left out dimes in his list of coins. He also left out the half dollar and dollar. While none of those left out coins could be the solution, John should have listed all possibilities.
I found the question imcomprehensible and English is my first language . the coins have the same value as one dollar and 6 coins. Is it a one dollar coin? All the coins are the same.!!!! So 7 dollars.
, but there were 10 coins!!
It would be so helpful if you could use the metric system like the rest of the world.
math is your problem not the lack of the use of the metric system.
got it. 4 coins = $1, must be .25 each. thanks for a fun one. 10 seconds...
10X (amount of coins) = 100 (ct) + 6X => 4X = 100 => X = 100/4 = 25 ct. = 1 quarter.
for c in range(100):
if 10*c == 6*c + 100:
print(c/100)
All I had to do is understand that I had 10 equal value coins, 4 of them were the same as a dollar, so the value had to be a quarter. The question doesn't imply that the 6 coins are less than a dollar, so it didn't matter that the total monetary value of the coins is $2.50. I didn't need algebra, I just used logic.
You are missing the point of a lot of his videos. Sure you can reason this and many other example problems out in your head by logic or common sense knowledge. The point is to be able to look at a word problem and learn to create an equation from the information given to you. Most people won't be able to solve more complex word problems that require more complex math by logic alone.
Greetings. The coin is $0.25. Four of the coins is (4×.25)=$1.00 since they are the same value.
ruled out all the coins that didn't make more than a dollar with 10 of them. Tested hypothesis by using six quarters equals 1.5 +a dollar equals 2.5 dollars divided by 10 it still holds true.
Where’s the dimes?
What level are your problems usually targeted for?
A quarter 1.06
Because the value is the same as one and 6 that equals 1.06$
I tried algebra but could not get further than the original equation: 10x = 1 + 6x. :(
I really need to practice my algebra.
But once you figure out the wording it's obvious.
Not to mention that there was only 4 options anyway.
the 1 is actually 100, one dollar is one hundred cents. or 1 = 4x or x = 1/4 dollar, and in the USA, that is a quarter coin.
@@darellpiper7227 In Canada too. But we don't have one cent coins anymore. ;)
She has 10 quarters. 4 of them equal $1. 6 of them equal $1.50.
Another coin is the dime (.10)
not the correct answer, 10 dimes does not equal $1.00 + 6 dimes.
@@darellpiper7227 Right. I just meant that John cited US coins and he left out the dime. Before solving, no one knew which was the correct one. Maybe he gave a "hint" by leaving it out and I missed it.
Help solve this problem. Jane bought a box of candies to re-sell at $3.5 each. She made a profit equal to 40% of her purchase price after she had sold 68 of them. What's her net profit after she sold all the candies in the box?
@James A. Holman: It's not said how many candies the box contained. I guess we have to use the given info to find it.
To work this problem I would require a check.
Why not just ask ann?
10 million dollars...hahaha 😂 All coins were rare error coins
USA has $0.10 coins, and$0.50 Coins also.
Quarter
3x25cents,2 nickels and one dime
Ann has 10 coins of the same value
Ann has $1 and 6 coins
So 4 coins must equal $1
The coins are Quarters
A FOURTEEN-MINUTE VIDEO on this? C'mon. 10x = 1 + 6x, thus 4x = 1, and x = 1/4 = a quarter. Done. I now have 13 minutes and 45 seconds left.
OK! I substracted 10x instead of 6x on both sides and got all confused. Oups!
10 quarters equals $2.50
25 cents
Quarters
The question is confusing.
10x = 1 + 6x Solved for x .
A querer is the coin and the math equals $2.50
They are quarters.
She has $2.50 in quarters.
10 coins of the same value that equal as much as one dollar and 6 coins...the coin is quarter...10 quarters equal $2.50 and so does one dollar and 6 quarters!!!!
25 cent coin?
The coin is a quarter.
4 coins= $1, 1 coin =25 cents.
she has 10 quarters
Qwartah
The problem seems more of trying to understand it than solve it.
Hopefully...
10c = $1 + 6c
4c = $1
c = $0.25
MORE FORMALLY:
this problem has one unknown
c : coin's value
given
10 coins eq.1
specifically
10 c = $1 + 6 c eq.1.1
one equation in one unknown
$1 = 10 c - 6 c
$1 = 4 c
c = $0.25
VERIFY
10 c = $1 + 6 c eq.1.1
c = $0.25
10(0.25) =? $1+6(0.25)
$2.50 =? $1 + $1.50
$2.50 =❤ $2.50✔️✔️
the relationship given is that
4क्वायन्स=1डालर
1क्वायन्स =1/4डालर
Ten cents ten times ten dimes six cents six times six pennies
what we have here is failure to communicate.
@@darellpiper7227 I am use English alphabet
took me 2 seconds to work it out in my head... took you 15 minutes to explain it. Get to the POINT already.
Quarter dollars, I wager, 2 bit a piece. Not in the bullshite bit coin way...
What do you have against dimes. LOL jk
dimes are the wrong answer it a true statement.
@@darellpiper7227 I was only noting that they were not there. Pennies and nickels were the wrong answer too
Kinda obvious
Well, obvious if you're in Canada or the US. Other countries would have trouble with this as they don't have coins with a value of 25 percent of the main denomination. For example, Australia has five, ten, twenty, and fifty cent coins. Technically, Canada has a 50 cent coin, too, but they're not distributed so you rarely see them. In Australia, you see their fifty cent coin all the time.
