Question

Corinne has a job selling magazines. She earns $7.50 per hour plus 20% of the total amount of her sales. She also gets an allowance of $40 per week for gas. She knows her weekly earnings can be shown using the following expression:

7.50h+0.20s+40

Answer 1

A) constant=40, coefficient=7.50, variable=h
B)7.50h+.20s+40
7.50(25)+.20(300)+40
187.5+60+40=287.5$
C)9.0h+.2s+40, So yes a coefficient would change, but nothing else
