Answer: 3
Explanation:
x + 7 = 5 x 2
you do 5(2) and get 10
plug in 10 and the equation looks like:
x + 7 = 10
from there you would subtract 7 from 7 and 10 to isolate x and get your answer of:
x = 3 :)
For On call = 10/3.5 = $2.85 for per hour
For talk time 1.25/1/2= $2.5 for per hour
We have two points so we can find the gradient using y1-y2/x1-x2
gradient = 21-27/2-8
= 1
we know the form for any linear equation is y = mx + c
we have m and a point so we can substitute in point (2,21) to find c
21 = 1 x 2 + c
c = 19
therefore, the equation is y = x + 19
