Answer:
<u>The future value of this investment after 10 years is US$ 5,152.58</u>
Step-by-step explanation:
1. Let's review the data given to us for solving the question:
Investment = US$ 2,500
Annual interest rate = 7.5% compounded annually
Duration of the investment = 10 years
2. Let's find the future value of this investment after 10 years, using the following formula:
FV = PV * (1 + r) ⁿ
Replacing with the real values, we have:
FV = 2,500 * (1 + 0.075) ¹⁰
FV = 2,500 * 1.0075¹⁰
FV = 2,500 * 2.06103
<u>FV = US$ 5,152.58</u>
In this question we have to find the effect of doubling principal, rate or time .
First we have to check the formula which is

As we see that interest is the product of principal, rate and time. So if any of these three doubles, that is if any of these three is twice of the original value, the interest gets doubled.
SO the correct option is C.
Answer:
The unit rate is 32/25 Walls per gallons.
Step-by-step explanation:
Gallons of paint used by Martin = 5/8 gallons
Portion of wall Martin wants to paint in pints = 4/5 wall.
Rate at which Martin paints the wall: Rate = Portion of wall covered/Paints Used.
Rate = 4/5 Gallons/5/8 Gallons = 32/25 Wall Gallons.
