antoniya [11.8K]

The amount of last year sales is $ 528400

<em><u>Solution:</u></em>

Let "x" be the amount of last year sales

Given that,

The total sales at Office Products this year are $713,340, which is 35% more than last year’s sales

Therefore,

This year sales = 35 % more than last year sales

This year sales = 35 % of last year sales + last year sales

713340 = 35 % of x + x

713340 = 35 \% \times x + x\\\\713340 = \frac{35}{100} \times x + x\\\\713340 = 0.35x + x\\\\713340 = 1.35x\\\\\text{Divide both sides of equation by 1.35 }\\\\x = 528400

Thus amount of last year sales is $ 528400

that is the number of feet. so then you multiply your number of feet by your cost per foot and you get 21.98
