Hello.

There is not enough information given in the problem to find the answer.
In order to find the calories in one apple, more information such as the total calories of the fruits in needed.

Please post the question with missing information.

Thank you.

apple=banana+13 이 아니라 banana=apple+13 이잖아요. 그리고 문제를 잘못쓴것 같은데 다시한번 읽어보시지요

Apple=p+20
Peach=p
banana=p+42(p+29=banana-13)
p+29+2p+p+42=4p+71
4p+71calories

Apple = Peach +29 = p +29
Banana = Apple +13 = (Peach +29) +13 = (p +29) +13 = p +42
Salad = Apple + 2 Peachs + Banana = (p +29) + 2p + (p + 42) = 4p + 71 calories
