Annuities
Suppose a fixed investment R is done every fixed number of periods m per year for t years at a constant rate r.
a.
The final value of the investments plus the interest is calculated as follows:

Where:
n = number of total periods of the investment.
n = m*t

The company invests R = $13,000 for t = 10 years at the end of every quarter (3 months), thus m = 4. The interest rate is r = 9% = 0.09.
The interest rate compounds quarterly.
Calculate:
n = 4*10 = 40
i = 0.09 / 4 = 0.0225

Calculating:
FV = $829,220
The company will have $829,220 in scholarship funds
b. The interest can be found by subtracting the final value and the initial value. We have to calculate the latter:

Thus, the interest is:
welcI = $829,220 - $340,516
I = $488,704
The interest is $488,704
Answer:

Step-by-step explanation:
Answer:
10, 11
Step-by-step explanation:
The square root of 100 is 10. Since 111 is larger, we know it is larger than ten, but not quite large enough to be 11.
You just need to make the denominator the same
tony has 7/8 candy bar = 70/80 candy bar
he wanted to make serving of 3/10 bar = 24/80 candy bar
total servings that he can make :
70 / 24
= 2.91 servings
hope this helps
