Question

Because of hiring a plumber, y, to work x hours on a repair project can be modeled using a linear function. the plumber charges a fixed cost of $80 plus an additional cost of $45 per hour. the plumber works a maximum of 8 hours per day

Answer 1

Answer:

The plumbers cost would be equal to the equation 80+45x=y with y being the total amount of money he made and x being how many hours he worked.

Step-by-step explanation:

In this equation to find the amount the plumber was paid all you need to do is plug in the amount of hours he worked for x.

If the plumber worked his maximum of 8 hours then the equation would change from 80+45x=y to 80+(45×8)=440.

So, if the plumber worked for 8 hours he would make $440.

Answer 2

The plumber will earn $440

Fixed cost charged = $80

Variable cost = $45 per hour

Therefore, the equation that will be used in calculating the amount earned will be: = 80 + (45 × x) = 80 + 45x

If the plumber works for 8 hours, the amount earned will be:

= 80 + 45x

= 80 + 45(8)

= 80 + 360

= $440

Therefore, the amount earned is $440
