Jim is an electrician. He charges a $150 home-visit fee and $45 per hour, with

the first two hours free. Which equation could elyse use to calculate the cost, c, to have Jim work at her house for 5 hours?



a. c 5 150 1 45(5)

b. c 5 150 1 45(5 1 2)

c. c 5 150 1 45(5 2 2)

d. c 5 (150 1 45)(5 2 2)

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
