Joan paid 14 an hr

Question

. JoAnn works in the publicity office at the state university. She is paid $14 an hour for the first 35 hours she works each week and $21 an hour for every hour after that. If she makes $742 one week, how many hours did she work?

Answer 1

Hi Jaila,

For the first 35 hours JoAnn works, she receives $14 for each hour. This would contribute the following amount to her total pay for the week:

35 x $14 = $490

The rest of her pay for the week in the problem will come from her pay of $21 for each hour.

To determine how many hours this would be for the week she earned $742, you would first subtract the $490 from her weekly pay to see how much money she earned at the higher rate of $21 an hour:

$742 - 490 = $252

Therefore, $252 of her pay was earned at $21 for each hour. The number of hours worked for this part pf the pay would be determined by :

$252 divided by 21 = 12 hours.

She worked 12 hours at the rate of $21 per hour.

The total hours worked would be the sum of the 35 hours and the 12 hours: 35 hours + 12 hours = 47 hours worked for the whole week.
