A 10 hours

B 2.5 hours

C 4 hours

D 6 hours

Answer 1

Answer:

D. 6 hours

Step-by-step explanation:

your equation is 50=5x+20

you then solve for x

50=5x+20

-20       -20

30=5x

divide both sides by 5

your answer is x=6

Answer 2

Answer:

D.

Step-by-step explanation:

You can set up and equation to solve for any cost like so:

5x + 20 = c

5x is the price for each hour

20 is the fixed fee

c is the total cost

Now let's use the price given to solve:

5x + 20 = 50

Subtract 20 from each side:

5x = 30

Divide each side by 5:

x = 6
