Kala will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $50 and costs an additional $0.13 per mile driven. The second plan has an initial fee of $55 and costs an additional $0.11 per mile driven.
For what amount of driving do the two plans coast the same in miles?
What is the coast when the two plans cost the same?

250 mi

Step-by-step explanation:

plan1:cost=50+0.13x

plan2 cost=55+0.11x

50+0.13x=55+0.11x

0.13x=55+0.11x-50

0.13x=0.11x+5

0.13x-0.11x+5

0.02x=5

x=5/0.02

x=250

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
