Answer:
x
-- = y
25
Step-by-step explanation:
Because it is 25% off, x is divided by 25 to get the price.
For example if x was 100, divide it by 25 you get 75, which is y.
There are 88 green marbles!
g=numGreenMarbles
b=numBlueMarbles
g+b=104
g=5b+8
b=104-g
g=5(104-g)+8=520-5g+8
g=88
Given:
2 years ago - consumer price index 1,200 per month
current year - consumer price index 1,400 per month
Inflation rate = [(Consumer price index current - Consumer price index previous) / Consumer price index previous ] * 100%
Inflation rate = [(1400 - 1200) / 1200] * 100% = (200 / 1200) * 100% = 16.67%
Since 2 years has passed, the 16.67% inflation rate is good for 2 years. We simply divide the inflation rate by 2 to get the annual inflation rate.
16.66% / 2 = 8.33%
The annual inflation rate for the past two years is 8.33%
