Question

A telemarketer earns $150 a week plus $2 for each call that results in sale. Last week she earned a total of $204. How many of her calls resulted in sales?

Answer 1

27 calls

Explanation:

Let T(x) represent total sales.

Then T(x) = $150 + ($2/call)x, where x is the number of calls made.

If T(x) = $204, we can solve for x, the number of calls made:

$204 = $150 + ($2/call)x, or

$ 54

----------- = 27 calls

$2/call
