Question

Janice worked to earn $7,136.10. Suppose she earns $79.29 per hour. Explain how Janice can figure out how many hours she worked to earn the money.

Answer 1

Answer:

90 hours

Step-by-step explanation:

set it up like this

7,136.10$/x = 79.29$/1hr

isolate for x by multiplying it to the right and getting it out of the denominator

7,136.10$ = 79.29$*x/1hr

multiply each side by 1hr to get rid of the division on the right side

7136.10$*1hr =79.29$*x

divide by 79.29$ on each side to isolate for x

7136.10$*hr/79.29$= x

the units cancel and your left with hours

7136.10*hr/79.29=x

finally just divide 7136.10 by 79.29

X= 90 hours

Hope this helps
