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
513x40 =20520
513x6=3078
That's all
