Answer:
The plan is:
A fixed cost of $50 per month.
An extra of $15 per GB used over the limit of 2B.
We can write this as a linear equation:
C(x) = $15*x + $50
C(x) is the monthly cost, and x is the number of GB that she used over the limit.
Then, if she used 3GB over the limit, we should replace x by 3.
C(3) = $15*3 + $50 = $45 + $50 = $95.
And the answer to the second question was already found, if she used xx GB in the month, then we have:
C(xx) = $15*xx + $50
(we replaced the x in the general equation by xx)
Answer:
The size of an angle is measured in degrees (see Angle Measures). When we say 'the angle ABC' we mean the actual angle object. If we want to talk about the size, or measure, of the angle in degrees, we should say 'the measure of the angle ABC' - often written m∠ABC.
