Alright, so in order to solve this problem, you need to know the formula for compound interest, which is
A= P(1+r/n)^nt
A is the final amount, P is the beginning amount, r is the rate it is being compounded at, n is the number of compounds per year, and t is obviously the time or number of years
Since it is compounded monthly, n will equal 12, as there are 12 months in a year.
Plug in what you have and you get A= 100 (1 + .06/12)^(12)(20)
A=331.02
Answer: 3.9ft²
Step-by-step explanation:
Find the area of the rectangle first:
= Length * Width
= 2 * 1.5
= 3 ft²
Find the area of the semi-circle by finding the area of a circle and dividing it by 2:
= πr²
= 3.14 * 1.5/2 * 1.5/2
= 1.76625ft²
Divide by 2:
= 1.76625/ 2
= 0.88 ft²
Add the area of the rectangle to the semi-circle:
= 3 + 0.88
= 3.9ft²
The first one is correct as the service fee plus the daily cost must be added to find the total cost which is less then $160.
