Answer:
$82.5
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.
