2. $15
--Explanation--
1. 15% off of 100 just means moving the decimal in 15 over by 2 to the left.
From there, multiply 100 x 0.15.
Then you get 15, so that's how much tax you are paying. Meaning Subtract 15 from 100 to get the price it originally was before tax. 100 - 15 = 85.
2. $15 dollars tax from moving decimal 2 to the left of 15%.

Step-by-step explanation:
For the first month it will be $40 for the service and $35 to activate the phone service. After the first month it will only be $40 but for the first month it will be $75
The square would be 100.
The semicircle you will use the formula πr^2/2.
That would mean you would take the 3.14x5^2/2.
(3.14x5x5)/2
(3.14x25)/2
78.5/2
=39.25
So the total area would be 139.25
