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:
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
