The cost of renting roller blades is $4 plus $3.50 for each hour that the roller blades are rented. Write an expression to repre

Pavel [41]

Answer:

The expression is equal to $3.50h+4$

Step-by-step explanation:

Let

x ----> the number of hours that the roller blades are rented

y ----> the cost of renting roller blades in dollars

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value of the linear equation

In this problem we have

The slope is equal to

$m=\$3.50\ per\ hour$

The y-intercept is equal to

$b=\$4$ ----> value of y when the value of x is equal to zero

substitute

$y=3.50x+4$

For x=h hours

substitute

$y=3.50h+4$
