Answer:
Step-by-step explanation:
let x represent the number of MB used in a month.
Let y represent the monthly cost of using x MB.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (36 - 24)/(7 - 3)
m = 12/4 = $3
We would represent the linear equation in the slope - intercept form which is expressed as
y = mx + c
Where
c = y intercept
m = slope
At the y intercept, x = 0. Therefore, the y intercept is the flat monthly fee of $15. It is charged whether MB is used or not. Therefore, the linear equation is
y = 3x + 15
Or
C(x) = 3x + 15
Answer:
1)65.9
2)326.6
3)13.6
4)8.0
Step-by-step explanation:
The trick is always to look at the number after the first decimal for rounding to 1 decimal place, if its above 5, you round it up to the next decimal; eg. 13.45 = 13.5 because the 5 will round it up,and if value below 5, you round it down; eg. 12.34 = 12.3 because the 4 is below 5 and the nearest 10th decimal is 3.
