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

The Answer: B Promise me ok Enjoy :D
Step-by-step explanation:
Answer: 153
Step-by-step explanation:
A straight line is a 180 degree angle.
If you subtract 38 from 180, you get your answer.
180 - 36 = 153
34*a = 64
a = 64/34
a = 32/17
Answer:
90*
Step-by-step explanation:
It’s 90 instead of 360 since it is only asking for THE angle x, not the sum of them
