15) A car salesman earns $700 per week plus 2.5% commission on his sales. If he sold two cars for a total of $75,000 last week, how much did he make?

Please help!

$2575

Step-by-step explanation:

For this problem, we need to form an equation that represents the car salesman's weekly income.  We are given that he makes at least $700 per week and that he makes 2.5% commission for his sales.  Let n represent the total amount of sales the car salesman made.  So we can build the equation as follows:

f(n) = 0.025n + 700

Note that if we let n = 0 (He made no sales) then he will make his minimum weekly income of $700.

So let's use our formula to calculate how much he made for the week given he made $75000 in sales.

f(75000) = 0.025(75000) + 700

f(75000) = 1875 + 700

f(75000) = 2575

Hence, the car salesman made $2575 for the week.

Cheers.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
