A car rental company has two rates. The first rate is $45 per day plus 29.5 cents per mile. The second rate is $90 per day plus 7 cents per mile. If you rented at the $90 rate, how many miles would you need to drive to break even?

a: 100 mi

b: 200 mi

c: 300 mi

d: 400 mi

B) 200 miles.

Step-by-step explanation:

Let    M = miles that you need to drive

45 + 0.295M  = 90 + 0.07M

90 - 45 = 0.295M - 0.07M

45 = 0.225M

M = 45/0.225

M = 200

Hope this helped :)

so it is 200 miles

Step-by-step explanation:

B) 200 miles.

Step-by-step explanation:

Let    M = miles that you need to drive

45 + 0.295M  = 90 + 0.07M

90 - 45 = 0.295M - 0.07M

45 = 0.225M

M = 45/0.225

M = 200

yes

step-by-step explanation:

give me the question

\

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
