Karen earned $33 in 4 hours at her job today. She wants to know how much she could earn tomorrow if she works 10 hours at the same hourly rate. How much will Karen earn in 10 hours?

$82.5

Step-by-step explanation:

Karen earns $33 in 4 hours of work she did today.

She considers working for 10hours to know how much she can earn.

We use direct proportion to solve this by saying; If Karen works for 4hours and earns $33. Mathematically, we say:

4 hour = $33

Thus,

1 hour = 33/4

= 8.25

Therefore, $8.25 is the pay per hour

Thus, if Karen works for 10 hours, she will earn a total sum of $8.25 × 10

= $82.5

Karen will earn a total sum of $82.5 if she works at the job for 10 hours at the same hourly rate.
