Sally's parents deposited $15,000 into a college savings account on her third birthday. The account had an interest rate of 9.6%
compounded annually. They were hoping that the money would double twice by the time she was 18 years old. Using the rule of

Yes, the $15,000 will double each 7.5 years. In 15 years, it will double twice.
Yes, the $15,000 will double in 7.5 years and be four times as much in 15 years.
No, the $15,000 will only double once in 15 years, not double twice.
No, it will take 30 years for the $15,000 to double twice.

The rule of 72 says to divide 72 over the interest rate without the percent sign attached to it. This means we divide 72 over 9.6 to get 72/9.6 = 7.5

So the money doubles every 7.5 years. When another 7.5 years rolls around, a total of 2*7.5 = 15 years has gone by. At this point the money is roughly 4 times that of the original amount deposited.

the solution is h=10 because you add 9 to each side of the equation.

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
