Answer:
$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.
