Question

Robert Downey Jr.'s costume rental shop charges $8 a day to rent a costume. Chris Evans' costume rental shop charges $6 a day and a $160 fee to rent a costume. For how many days would it be the same cost to rent a costume from either shop?
need the equation with variables on both sides​

Answer 1

Answer:

80 days

Step-by-step explanation:

Start off by making the two equations.

t = total cost

d = days

Robert Downey Jr.'s equation would be:

t = 8d

Chris Evans' equation would be:

t = 6d + 160

Now, set them equal to each other:

8d = 6d + 160

Then, solve for d:

8d = 6d + 160

Subtract 6d from both sides:

2d = 160

Divide both sides by 2:

d = 80 days
