On April 1, the price of gas at Bob's Corner Station was $3.50 per gallon. On May 1, the price was $4.25 per gallon. On June 1, it was back down to $3.50 per gallon.
Between April 1 and May 1, Bob's price increased by

Suppose that at a gas station across the street, prices are always 20% higher than Bob's. In absolite dollar terms, the difference between Bob's prices
and the prices across the street is when gas costs $4.25 than when gas costs $3.50.
Some economists blame high commodity prices (including the price of gas) on interest rates being too low.
percentage points means that the Fed raised
Suppose the Fed raises the target for the federal funds rate from 2% to 2.5%. This change of

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

central angle of a triangle has the same measure as its intercepted arc.
