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

C = 10m + 30, where C is total cost and m is # of months

C = 10(5) + 30

C = 50 + 30

C = $80

$160 = 10m + 30

160 - 30 = 10m

130/10 = m

m = 13 months

25 out of 27 as a percentage
Basile [38]
25/27 = 0.925925925...

It's almost equal to 1 and it turns out that 1 is 100%.

So, we'd say that it's equal to:

92.59% (to 2 decimal places)

We've multiplied the value above (25/27) by 100.
