$220 is a flat amount of his pay, so

$448.50 - $220 = $228.50 represents the amount earned by commission.

So $228.50 is 7.5% of total sales.

Mathematically, this can be expressed

228.50 = 7.5 / 100 x X, where X is the total sales.

Solve for X by multiplying both sides by the inverse fraction 100/7.5:

X = 228.50 x 100 / 7.5

You'll find this matches one of the options!
