A truck can be rented from Company A for $100 a day plus $0.70 per mile. Company B charges $70 a day plus $0.90 per mile to
rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
1 answer:
Answer:
The cost of renting will be the same for 150 miles.
Step-by-step explanation:
Let n the number of miles and C be the cost. We can represent the cost equations for each companies:
A: C = 100 + 0.7n
B: C = 70 + 0.9n
They want to know when the cost will be the same, so we can set the above 2 equations equal to each other and solve for n:
100 + 0.7n = 70 + 0.9n
0.2n = 30
n = 150

Point of Y intercept is (0,4)
Y1-Y2=m(X1-X2)
Plug in x,y into X2, Y2 m=slope
y-4=2(x-0)
y-4=2x
y=2x+4
