Boris gets an 8% commission on every car he sells.Last week, he made a commission of $1,240.What was the price of the car he sold?
Do a proportion:
8% is 8 over 100 or:
8/100 and you know his commision is commision over the price. his commision is 1240, and you don't know the price. so lets use "x" in place of the price. so the commsion is equal to 8%:
8/100 is eqaul to commision/price or:
8/100 = 1240/x
now you solve for x by cross multiplying and dividing.
When you cross multiply you multiply 8 by x and 1240 by 100. Then you get 124000/8 and you get 15500
To solve for x, you can cross multiply and divide. The equation is:
8/100 = 1240/x
To cross multiply, you multiply 8 and x, and multiply 100 and 1240. This gives you:
8x = 100 * 1240
Now, you can divide both sides of the equation by 8 to isolate x:
x = (100 * 1240) / 8
Calculating the right side of the equation gives you:
x = 15500
Therefore, the price of the car that Boris sold was $15,500.
