At a carnival a food stall sold bags of cotton candy for $5 each and bags of popcorn for $7 each. A total of 140 bags were sold for $820. How many bags of cotton candy did the stall sell?

Respuesta :

The equation solved shows that the bags of cotton candy that the stall sell will be 80 bags

How to compute the equation?

Based on the information given, the equation to solve the question will be:

c + p = 140

5c+ 7p = 820

Multiply equation i by 5

Multiply equation ii by 1

5c + 5p = 700

5c + 7p = 820.

Subtract the equation

2p = 120

p = 120/2

p = 60

Therefore, the bags of cotton candy that the stall sell will be:

= 140 - 60

= 80
