The company will break even when the cost is equal to the revenue.
C(h)=R(h) \\
20h^2+160=400+220h \\
20h^2-220h+160-400=0 \\
20h^2-220h-240=0 \ \ \ \ \ \ \ \ \ \ \ |\div 20 \\
h^2-11h-12=0 \\
h^2+h-12h-12=0 \\
h(h+1)-12(h+1)=0 \\
(h-12)(h+1)=0 \\
h-12=0 \ \lor \ h+1=0 \\
h=12 \ \lor \ h=-1


The number of hours must be a positive number, so h=12.

The company breaks even after 12 hours.

Answer:

d) 5/3 x

Step-by-step explanation:

You substitute a for 2c and b for 5d, so your equation will look like this:

c/d - 2c/5d = x

Then you just simplify into x by making c/d into 5c/5d so you have a common denominator.

5c/5d - 2c/5d = x

3c/5d = x

5/3 is your answer

Answer:

The expressions for the payment made to Mary are,

(Monday) 90 = 15m + b

(Tuesday) 62 = 8m + b

where m and b are the fee per student and the base fee, respectively. Solving for m and b, the values are 4 and 30.

The equation that represents Mary's earning is

y = 4x + 30

For 20 students,

y = 4(20) + 30 = 110

For Lisa's earnings,

y = 8x + 15

Substituting 20,

y =8(20) + 15 = 175

Thus, Lisa would earn more than Mary by $65.

(Btw this is not my work, I got it from someone else on brainly and wanted to help lol)
