Question

HELP! PLEASE! THIS IS MATTER OF LIFE AND DEATH!!

The rental car charges $25 plus a fixed charge per mile. For the use of 210 miles the rental car was charged $67. What would be the cost of the rental car for 510 miles of use?

Is the answer

Answer 1

lil dramatic..but anyways
y=mx+25 (point (210, 67)
67= m(210)+25

Answer 2

solve for m

Answer 3

How..?

Answer 4

Take away 25 from both sides?

Answer 5

yes

Answer 6

42 = m(210)

Answer 7

yup

Answer 8

What do you do after that..?

divide each side by 210?

Answer 9

yes

Answer 10

.2 = m

Answer 11

that's what i got.
So now you have a formula to calculate the missing value
y=.2x +25

Answer 12

x represents miles y=price

Answer 13

y = .2(500) + 25

Answer 14

its 510 miles (but close)

Answer 15

y = 100 + 25
y = 125

Answer 16

its not 500*.2 it is 510*.2, so it would be 102+25 (but you had the right idea)

Answer 17

No..but apparently, the answer was $two hundred something..said my algebra teacher..

Answer 18

really i find that hard to believe. If they were able to go 210 miles for 67%, going a little more than double that should not be over 200

Answer 19

*$67


But anyways. I guess you're right. I hope we got it right..?

Answer 20

hope so =o

Answer 21

I thought the equation was y = 25x + 67

why was I wrong?

Answer 22

from the way the question is written it says that the rental car is charged 25 and a fixed amount per mile. the 25 dollars is not dependent upon the distance traveled
