Question

A vending machine collected $53 in sales the past week. This is a 6% increase from thesales the previous week. How much was collected the previous week?

Answer 1

The vending machine collected an amount of $53 in the past week which is 6% more than the sales from prevoius week

So

Sales in Past week = 6% of sales in Previous week + Sales on Previous week

let the sales in previous week = $x

So,

$6\text{ Percent of x=0.06x}$

So, the equation will be

$\begin{gathered} 53\text{ = 0.06x +x} \\ 53=1.06x \\ x=\frac{53}{1.06} \\ x=50 \end{gathered}$

So, in the previous week she collected an amount of $50

Answer : $50
