An apple has 24 fewer calories than a banana. If 7 bananas have the same number of calories as 10 apples, how many calories are in a banana?
------------
Equations:
a = b-24
7b = 10a
---------------
Substitute for "a" and solve for "b":
7b = 10(b-24)
7b = 10b-240
3b = 240
b = 80 (# of calories in a banana)
