Respuesta :

Answer:

15 chips and 8 pretzels

Step-by-step 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
