Question

At a lunch stand, each hamburger has 50 more
calories than each order of fries. If 2 hamburgers and
3 orders of fries have a total of 1700 calories, how
many calories does a hamburger have?

Answer 1

let the number of calories in fries be n

=> number of calories in hamburger = n+50

ATQ

2(n+50) + 3× n = 1700

=> 2n+ 100 +3n = 1700

=> 5n = 1600

=> n = 320

Hence, hamburger has 370 calories
