Answer:
$21.25
Step-by-step explanation:
100 - 15 = 85
25 * 0.85 = 21.25
Answer:
wrong it is 667.95
Step-by-step explanation:
For this case, the first thing to do is to use the equation of the given line.
We have then:
f (x) = 0.76x + 42.39
We substitute the value of x = 15:
f (15) = 0.76 * (15) + 42.39
f (15) = 53.79
Then, subtracting with the original value we have:
53.79-52.04 = 1.75
Answer:
the residual for when x = 15 is:
1.75
