Answer:
35 + .2m
Step-by-step explanation:
The monthly fee of $35 is a base pay, and you don't change anything with it.
The "m" stands for minute, and since it costs $.20 for each minute, multiply the two together to get that part of the equation.
Answer:
The fee increased 12.5%
Step-by-step explanation:
The new price is 9 and the old price is 8, so you can find the change by doing
9/8
which is 1.125
This means the new price is 12.5% higher than last year because you have to ignore the 1 in front and only look at the .125
Move the decimal place two to the right to get 12.5 and then add the % sign.
