The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Then the greatest common factor is 12.
The number of credit hours a student have to take for the two tuition costs to be equal is 2.5 hours. Option A
c(h) = 250 + 200h
s(h) = 300 + 180h
Where,
To have equal tuition in both schools,
equate both function
250 + 200h = 300 + 180h
200h - 180h = 300 - 250
20h = 50
h = 50/20
h = 2.5 hours.

A. 136 sq. units is the answer. This answer was achieved by simply plugging the numbers into the area formula for rectangles. 8 x 17 = 136
Answer:
7x
Step-by-step explanation:
(5.2 + 6.8)x - (25 ÷ 5)x
12x-(25divied by 5)x
12x-5x
Profit P(x) = 53x-12 and On selling 20 video games profit will be 1048.
In the given question functions are Revenue function : R(x) = 60x and Cost function : C(x) = 12+7x for the sale of x video games
As we know profit = sale price - cost price
Therefore P(x) = R(x) - C(x)
Or P(x) = (R-C)x = 60x - (12+7x)
P(x) = 60x -12 - 7x
P(x) = 53x -12
Now the profit on selling 20 video games will be
P(20) = 53×20 -12 = 1060 -12 = 1048.
