Answer:

$840

Step-by-step explanation:

52 - 40 = 12

12 hours overtime

12 * 20 = 240

40 normal hours

15 * 40 = 600

600 + 240 = 840

$840

Answer:

C. 840

Step-by-step explanation:

First, solve for the hours above 40.

Since she worked 52 hours, we can subtract 40 from 52 to find the amount of hours she worked overtime.

52-40=12

Since we know that overtime hours are worth more, we can multiply the 12 extra hours by 20.

12*20=$240

Now we need to calculate for her regular hours.

She worked 40 regular hours, so lets multiply that by her regular rate per hour.

40*15=$600

Now add both values for the total income.

600+240=$840

The answer is C. $840

Hope this helps!
