Question

a sugar dud has 30 less than twice as many calories as a krunchy krum if 5 sugar duds have the same number of calories as 8 krunchy krums how many calories are in each

Answer 1

Explanation:

8k, s = 8k/5, k = 5s/8 s = 2k - 30 s = 2 (5s/8) - 30

s=2k - 30

5s = 8k

5*(2k -30) = 8k

10k - 150 = 8k

2k = 150

k = 75, the number of calories in a krunchy krum. this makes s = 120 calories for a sugar dud
