Answer:
cost of popcorn bag is 6.5
Step-by-step explanation:
Here, we want to find the cost of a popcorn bag
let the cost of a bag of popcorn be p
let the cost of a bag of candy bar be c
Mathematically;
28p + 40c = 282
17p + 20c = 160.50
Multiply ii by 2 and subtract from i
28p + 40c = 282
34p + 40c = 321
34p-28p = 321-282
6p = 39
p = 39/6
p = 6.5
