Question

Martin earns $7.50 per hour proofreading ads at a local newspaper. His weekly wage can be found by multiplying his salary times the number of hours h he works.

Write an equation for Martin's weekly wage.
a) W = $7.50 — h
b) W = $7.50 - h
c) W = $7.50 · h
d) W = $7.50 + h
Find W(15), which represents Martin's weekly wage if he works 15 hours.
a) W(15) = $112.50
b) W(15) = $8.00
c) W(15) = $120.00
d) W(15) = $7.00
Find W(14), which represents Martin's weekly wage if he works 14 hours.
a) W(14) = $105.00
b) W(14) = $6.00
c) W(14) = $96.50
d) W(14) = $1050.00

Answer 1

The equation for Martin's weekly wage is c) W = $7.50 · h. For 15 hours of work, Martin earns a) W(15) = $112.50. For 14 hours, he earns a) W(14) = $105.00.

Step-by-step explanation:

The student's question involves determining an equation for Martin's weekly wage based on his hourly rate of earnings and calculating his wage for specific numbers of hours worked. To create an equation for Martin's weekly wage, we multiply his hourly wage by the number of hours he works. The correct equation is c) W = $7.50 · h, where W represents his weekly wage and h represents the number of hours worked. To find W(15), which is Martin's wage for 15 hours of work, we substitute 15 for h in the equation, resulting in W(15) = $7.50 · 15, which equals a) W(15) = $112.50. Similarly, for W(14), which represents his wage for 14 hours of work, we perform the calculation W(14) = $7.50 · 14, leading us to a) W(14) = $105.00.
