A truck can be rented from Company A for $100 a day plus $0.20 per mile. Company B charges $60 a day plus $0.70 per mile to

denis23 [38]

Answer:

Step-by-step explanation:

First, we write the rental cost with each company:

Company A $Pa = 100 + 0.2*m$

Company B $Pb = 60 + 0.7*m$

Where m: miles travelled

Now, we need to find "number of miles in a day at which the rental costs for Company A and Company B are the same". This means Pa = Pb. Then:

$100 + 0.2*m = 60 + 0.7*m$

Solving the equation for m by taking 0.2m and 60 on both sides:

$100 + 0.2*m - 0.2*m - 60 = 60 + 0.7*m - 0.2*m - 60$

$40 = 0.5*m$

Finally, dividing 0.5 on both sides:

$m = 80$
