Melissa will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $65 and costs an

OleMash [197]

Answer:

Melissa needs to drive 325 miles for the two plans to cost the same

Step-by-step explanation:

Initial Fee = 65

Additional cost per mile = 0.50 per mile

Initial Fee = 0

Additional cost per mile = 0.70 per mile

Required

Mile both plans will cost the same

Let

$y \to cost$

$x \to miles$

So, we have:

$y = Initial\ Fee + Additional * x$

For plan A

$y = 65+ 0.50* x$

$y = 65+ 0.50x$

For plan B

$y = 0 + 0.70*x$

$y = 0.70x$

So, we have:

$y = 65+ 0.50x$ --- plan A

$y = 0.70x$ --- plan B

Both plans will cost the same when

$y = y$

$0.70x = 65 +0.50x$

$0.70x -0.50x= 65$

$0.20x= 65$

Divide by 0.20

$x= 325$
