EASY PLEASE HELP 13 POINT'S Amanda rented a bike from Jill's Bikes. It cost $18 plus $4 per hour. If Amanda paid $50, then she rented the bike for how many hours?

Number of hours Amanda rented the bike =

Amanda rented the bike for about 17 hours.

17 hours

Step-by-step explanation:

50 + 18 = 68 divided by 4 = 17

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
