Two rentalcar companies charge different prices when you rent a car. company a charges $.28 per mile and a $50 fee. company b charges $.78 per mile but no fee. for what number of miles will the two companies charge the same price?

100 miles

Step-by-step explanation:

Create equations.

Company A: y = 0.28x + 50

Company B: y = 0.78x

These are equal to each other.

0.78x = 0.28x + 50

0.5x = 50

x = 100

7

step-by-step explanation:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
