Step-by-step explanation: Happy to help :)
You could understand the ration as parts: the total number of parts was 3+7=10.
So girls were 3/10 parts and boys 7/10 parts. The difference was 7-3=4 parts. this difference is equal to 360, so each part is 90 (4*90 =360).
so girls are "3 parts" and each part is 90, then the number of girls is 3*90=270.
For the first one take the amount the pitcher can hold and multiply it by the amount of pitchers he makes
14.5 x 8 = 116 oz
For the second one take the amount made per oz and multiply it by the amount of oz he made
0.25 x 116 = $29
