You got question 22 slightly mislead or confusing at 32:39 . 16.23 x 4.55 is actually 73.85 rounded up but on the calculator its 73.86 if you choose to times the answer (from 560 divide 34.5) straight away. Same with at 33:05 , 73.86 x 1.08 is actually 79.77 when you do it like that on the calculator, but if done straight away from the previous answer only then it gives you 79.76. Not trying to be nitpicky here but some people may not realise this.
Q22) The first part of the question is correct. 560/34.5=16.23 Gallons, but when you converted in to Gallons you should of calculated 16.23x4.55 to get 73.85. Next times 73.85 by 1.08 to get 79.6 Pounds.
Q15, you got the right answer but you did 630/70 but the question said 680 so technically it was 9.71 weeks, which can't be 10 weeks because it is looking for the nearest week which is 9.

They changed the answer when pressing the Ans button.
The video didn't separate the the 16.23 gallons by 4.55 which altered the answer by a decimal place
