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

<h3>How to compute the equation?</h3>

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
