In A plumber charges a fixed fee of $75 to make a service call, plus an hourly rate of $40. Dayshaneeds to hire the plumber for a job that will take 6 hours. Write and solve an equation for the total cost of the job.

$315.00

Step-by-step explanation:

You'll probably use the equation y=mx+b

so set up the equation as y= 40x + 75

75 is your flat fee and 40 is your hourly pay.

SOLVE FOR "X"

In this question our X is already given to us, "X" is 6

So y= 40(6) + 75

So 40 x 6 = $240

Then add your flat fee of $75

So $315

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

15 batches are the most you can make
