4. Mr. Crankshaft is a used car salesman. He keeps 5% of his sales as a commission. How much does he have to sell to earn $1000?

Answer :

ANSWER

$20,000

EXPLANATION

We want to find how much Mr Crankshaft has to sell to make a commission of $1000.

Let the amount he sells be x.

Since the commission rate is 5%, it means that 5% of x must be equal to $1000 (his commission).

Therefore, we have that:

[tex]\begin{gathered} \frac{5}{100}\cdot x=1000 \\ \Rightarrow x=\frac{1000\cdot100}{5} \\ x=\text{ \$20,000} \end{gathered}[/tex]

He has to sell $20,000.
