Answer:
The temperature in °F after x hours will be given by, y = - 8 + 2x.
Step-by-step explanation:
The temperature in the morning was - 8°F. Now, as the day went on the temperature rose 2°F each hour.
So, after x hours the temperature will rise by 2x°F.
Therefore, the temperature in °F after x hours will be given by, y = - 8 + 2x. (Answer)
Answer:
10%
Step-by-step explanation:
20%=20/100=0.20
75$x.0.20=15$
The price when she received a 20% discount was:
75$-15$=60$
Then, the web site applied a 10% service fee to the discounted price, so you have:
10/100=0.10
75$x0.10=7.5$
60$+7.5$=67.5$
So, if 75$ is the 100% of the price, what percentage represents 67.5$?
75$--------100%
67.5$------x
x=67.5 x 100/75
x=90%
Then,
100%-90%=10%
