Liz works at a computer outlet. She receives a weekly salary of $300 plus 5% commission on her sales. Assuming she makes sales worth $x in week. Her commission on $x sales would be

5/100 × x = 0.05x

The expression for her total earnings for the week would be

0.05x + 300

Last week, she sold $18,700 of computer equipment. Substituting 18700 for x, her total salary for the week would be

(0.05 × 18700) + 300

= 935 + 300 = $1235
