Answer:

40

Step-by-step explanation:

y = 50 + .4 x 40

y = 30 + .9 x 40

y = 66 for both equations

Answer:

Step-by-step explanation:

If in doubt, model the situations as a system of equations and then attempt to solve!

It'll let m be the number of miles in these equations.

Cost of A = 50 + 0.4m

Cost of B = 30 + 0.9m

Set these equations equal to each other to find what value of m makes them equal:

50 + 0.4m = 30 + 0.9m

Subtract 0.4m from both sides:

50 = 30 + 0.5m

Subtract 30 from both sides:

20 = 0.5m

Multiply both sides by 2:

40 = m

Therefore, the prices are equal at 40 miles.
