The total cost function is the sum of the two given functions, and this is equal to:

c(t) = 190 + 70*t

<h3>How to find the linear function for the total cost?</h3>

We know that:

  • The plumber charges p(t) = 115 + 25*t
  • The electrician charges e(t) = 55*t + 75.

If she hires both of them for the same time t, then the total cost function will be given by the sum of the two above functions, we will get:

c(t) = p(t) + e(t)

c(t) = (115 + 25*t) + (55*t + 75)

c(t) = (115 + 75) + (55*t + 25*t)

c(t) = 190 + 70*t

<h3>How to calculate commision on a cost of good</h3>

Commision is the percentage on a cost of good. GIven the following parameters

Cost of good = $2,617.75

If your broker charges a commission of 5.1% of the cost, the amount charged is given as:
