Question

18. Nine cartons of juice cost the same as 5 fruit cups. Also, one fruit cup costs 50¢ more than one bowl of soup, while one bowl of soup costs 50¢ more than one carton of juice. What would be the cost of each item: a carton of juice, a fruit cup, and a bowl of soup?​

Answer 1

Answer: bowl of soup=$1.75

carton of juice=$1.25

fruit cup=$2.25

Explanation:

j=carton of juice. f=fruit cup. s=bowl of soup.

9j=5f

f=s+0.5 ==> 0.5 dollars is 50 cents

s=j+0.5

j=s-0.5

9(s-0.5)=5(s+0.5)

9s-4.5=5s+2.5

4s-4.5=2.5

4s=7

s=7/4

s=$1.75

s=j+0.5

1.75=j+0.5

j=$1.25

f=1.75+0.5

f=$2.25
