The cost, (x), for parking in a city lot is given by c(x) = 3x + 4.00, where x is
the number of hours. what does the slope mean in this situation?
a. the rate of change of the cost of parking in the lot is $3.00 per
hour.
b. the rate of change of the cost of parking in the lot is $4.00 per
hour.
c. it costs a total of $4.00 to park in the lot.
d. parking in the lot costs $3.00 per car.

Option A

Step-by-step explanation:

we have

x > is the number of hours

c(x) > is the cost for parking in a city lot

we know that

c(x)=3x+4.00

This is a linear equation in slope intercept form

where

the rate of change or slope m is equal to m=$3 per hour

the y-intercept is equal to b=$4.00 (this is the cost when the number of hours is equal to zero)

therefore

The rate of change of the cost of parking in the lot is $3.00 per

hour

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
