Alandscaping company charges a $12 fee to make a house call plus an hourly rate for labor. if the total bill for a job that takes 2.5 hours comes to $95.75, write an equation that can be used to solve for the hourly labor rate. use r to represent the rate.

Step-by-step explanation:

This problem is solved using the linear function formula:

Where:

y= total bill

x= number of hours worked

b=fee

We have to find "a" in order to have the complete equation. We know that the constant fee (b) is 12$, and that if the hours worked are of 2.5 the total bill is $95.75, so we supplant on the equation and isolate "a".

So now we have the complete equation:

i am thinking c. sorry if im wrong .

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
