Question

3) The cost of a movie ticket and a candy bar is $5. The cost of 2 tickets

and a candy bar is $8.75. How much is a candy bar? *

Answer 1

$1.25

Explanation:

Given data

let the movie ticket be x and the candy bar be y

x+y= 5-------------1

also

2x+y= 8.75--------2

solve 1 and 2

x+y= 5

2x+y= 8.75

from 1

x= 5-y

put this inplace of x in 2

2(5-y)+y=8.75

10-2y+y= 8.75

10-y= 8.75

10-8.75=y

y= 1.25

Hence candy bar is $1.25
