Question

Terry earns a 250$ salary plus $5 per sale . How many sales must terry make to earn 765$ altogether?

Answer 1

103 sales

Explanation:

The equation governing his earnings is E(x) = $250 + ($5/sale)x, where x is the number of sales made. If the earnings are $765, then

$765 = $250 + $5x

Simplifying this, we get $515 = $5x, and so x = $515/$5 = 103 sales
