Joseph is an electrician who charges a travel fee to each customer. He also charges an hourly fee of service. The table below represents how much he charges for up to 5 hours of service. H C

0 35
1 95
2 155
3 215
4 275
5 335

Which equation represents the cost, C , of H hours of service?

A: C=35h-60

B: C = 35h + 60

C: C=60h - 35

D: C = 60h +35

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

step-by-step explanation:

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
