Answer: T
he number of miles in a day at which the rental costs for Company A and Company B are the same is when x = 160miles.
Step-by-step explanation:
Step 1
Let us write the rental cost with each company:
Company A , they will charge =$160 +$ 0.40x
Company B, They will charge = $80 + $0.90x
Where x =number of miles travelled
Step 2
we then find the number of miles in a day at which the rental costs for Company A and Company B will be the same by equating both equations and solving for x
160 + 0.40x= 80 + 0.90x
160-80 = 0.90x-0.40x
80= 0.50x
x= 80/0.5
x= 160
Therefore t
he number of miles in a day at which the rental costs for Company A and Company B are the same is when x = 160 miles.
