during a football game the parents of the football players sell pretzels and popcorn to raise money fir new uniforms they charge
GrogVix [38]

Answer:

96 bags of popcorn and 48 pretzels

Step-by-step explanation:

Let

x ----> the number of bags of popcorn sold

y ----> the number of pretzels sold

we know that

2.50x+2y=336 ----> equation A

x=2y ---> equation B

Solve the system by substitution

Substitute equation B in equation A and solve for y

2.50(2y)+2y=336

5y+2y=336

7y=336

y=48 pretzels

Find the value of x

x=2(48)=96 bags of popcorn
