Bob picked 450 apples for his entire family to eat. There are 33 children in his family, and each of them ate 10 apples. If every adult ate 3 apples apiece, how many adults are in his family?
The 33 children ate a total of 33 * 10 = <T>multiply(33, 10)=330 apples.
There were 450 - 330 = <T>subtract(450, 330)=120 apples left for the adults to eat.
If every adult ate 3 of the 120 apples left, then there were 120 / 3 = <T>divide(120, 3)=40.0 adults in the family.
