A.
277.8°F
B.
201.8°F
C.
125.8°F
D.
525°F

Answer:
He should work hours in overtime.
Step-by-step explanation:
Let x represents the number of hours of regular time and y represents the number of hours of overtime,
Since, earnings are $24 per hour for regular time and $36 per hour for overtime,
Thus, total earning = (24x + 36y) dollars,
Here, x = 40 hours and total earning = $ 1200,
By substituting the values,
1200 = 24(40) + 36y
1200 = 960 + 36y
240 = 36y
⇒
Hence, he should work hours in overtime.
<u><em>r=-199/80 is the right answer.</em></u> First, you had to multiply by 100 from both sides of the equation. And it gave us, . Next, you had to refine, and it gave us,
. Then, subtract by 1470 from both sides of equation. And it gave us,
. Simplify, and it gave us,
. You can also divide by 320 from both sides of equation. And it gave us,
. And finally, simplify, and it gave us the answer is <em><u>r=-199/80 is the right answer.</u></em> Hope this helps! And thank you for posting your question at here on brainly. And have a great day! -Charlie
