Acomputer repair person charges $50.00 per hour, plus an additional mileage fee. the charge for mileage varies directly with the square root of the number of miles traveled. if one hour plus 25 miles traveled costs $140.00, what is the total amount charged for one hour plus 36 miles traveled? can someone me with this problem asap.

$ 179.6

Step-by-step explanation:

Given,

The charges per hour = $ 50.00

Suppose x be the additional mileage fee ( in dollars ) for each miles,

So, the total fees for 1 hour and 25 miles = 50 + 25x

According to the question,

50 + 25x = 140

25x = 90

⇒ x = = $ 3.6

Thus, the additional mileage fees is $ 3.6 per hour,

Hence, the total amount charged for one hour plus 36 miles traveled = 3.6(36) + 50 = $ 179.6

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
