The number of customers served in the ice cream shop in June, July and August are 125, 25 and 250 customers respectively
<h3>How to write and solve equation?</h3>
let
- June = x
- July = x - 100
- August = 2x
- Total customers = 400
Total = June + July + August
400 = x + (x- 100) + 2x
400 = x + x - 100 + 2x
400 = 4x - 100
400 + 100 = 4x
500 = 4x
x = 500/4
x = 125
So,
June = x
= 125 customers
July = x - 100
125 - 100
= 25 customers
August = 2x
= 2(125)
= 250 customers
