To solve, isolate the x. Cross multiply

3/13(13)(5) = x/5(5)(13)

3(5) = (13)x

Simplify

13x = 15

Isolate the x. Divide by 13.

13x/13 = 15/13

x = 15/13

x = 1.2

1.2 is your answer

hope this helps

You receive an 11 percent commission on all sales you make if your commission for the month is 512.50 dollars what was your tota
JulijaS [17]

Total sales were $4659.1

Step-by-step explanation:

Given,

Commission = 11%

Amount of commission = $512.50

Let,

total sales = x

Therefore,

11% of x = 512.50

\frac{11}{100}x=512.50\\0.11x=512.50

Dividing both sides by 0.11

\frac{0.11x}{0.11}=\frac{512.50}{0.11}\\x= $4659.1

Total sales were $4659.1
