Question

The amount of money an electrician charges when visiting a home to make a repair is shown by the linear equation c = 120 + 65h, where c is the amount the electrician charges and h is the number of hours spent at the home.



How much does the electrician charge when h = 2.5?

Answer 2

You can put 2.5 into the equation for h and then just solve

Answer 3

write down the equation
c = 120 + 65h

erase the h and put in 2.5 in its place (and remember 65h means 65 times h)
then simplify (remember order of operations... multiply first)

Answer 4

c = 120 + 65 (2.5)

Answer 5

so its 185 @Ashes.boom
