First lets remove the initial fee

150 is how much she is charging you per hour.
If each hour is 55, lets divide 150 by 55.

She charged you for 2.7 hours (almost 3) of service
B if you need an explain I can do it

Step-by-step explanation:
If the coin Shun is flipping is 2 sided the most linear anwser would be to make the prediction of it flipping on the tails side for a perfect total of 225.
Answer:
(-12,2)
Step-by-step explanation:
2x + 4y = -16
2y - x = 16
Multiply the bottom part by 2.
2x + 4y = -16
4y - 2x = 32
Add the equations and the answers to the equations up, and they will equal each other.
(2x + 4y) + (4y - 2x) = -16 + 32
8y = 16
y = 2
Plug y = 2 to the 2nd equation.
2*2 - x = 16
4 - x = 16
Subtract 4 from both sides.
-x = 12
Multiply both sides by -1.
x = -12
