Question

Melania has two jobs. During the day she works as an office clerk, and in the evening she works as a cashier. Her office job pays her $13 per hour. Her cashier job pays her $9.25 per hour. In one week, Melania worked 38 hours. She earned a total of $434.

Let c represent the number of hours that Melania works as an office clerk. Which equation can be used to find how many hours Melania worked in both jobs?

A.
13c + 9.25(c – 38) = 434

B.
13c + 9.25(38 – c) = 434

C.
13c + 9.25(434 – c) = 38

D.
9.25c + 13(38 – c) = 434

Answer 1

if she works 38 total hours as a cashier and office clerk, and c is the number of hours worked as an office clerk, then 38-c is the number of hours worked as a cashier

multiply the number of hours for each job by the pay rate for that job, add together, and set equal to the total earnings. that's your equation...
