Find the number of calories in a banana and a peach. 1) A banana contains 65 more calories than a peach. 2) Eight peaches have 20 fewer calories than 3 bananas.

Answer:

Let number of calories in a banana = b
and number of calories in a peach = p
Then 1) b = 65 + p
2) 8p = 3b - 20

This gives p = 35 and b = 100
