Question

Helen spent 7.75 to purchase 23 snack sized bags of chips (c) and pretzels (p). Chips cost 0.25 and pretzels cost 0.50. How much of each type of snack did she get?

Answer 1

15 chips and 8 pretzels

Explanation:

According to the problem, calculation of the given data are as follows,

Total spent = $7.75

Number of snacks = 23

Chips cost = $0.25

Pretzels cost = $0.50

Let number of chips = X

So, number of pretzels = 23 - X

So, we can calculate number of snacks by using following equation

0.25X + 0.50 ( 23 - X) = $7.75

0.25X + 11.50 - 0.50X = 7.75

0.25X - 0.50X = 7.75 - 11.5

-0.25X = -3.75

X = -3.75 ÷ -0.25 = 15

Hence, Number of chips = 15

Number of Pretzels = 23 - 15 = 8
