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

Answer:
13.6
Step-by-step explanation:
The measure of the segment AQ is related to the measure of the segment A'Q by the dilation factor as follows:
dilation factor = A'Q/AQ
AQ = A'Q/dilation factor
Replacing with data:
AQ = 2.4/0.15 = 16
Then, the distance between points A and A' is
x = 16 - 2.4 = 13.6
