Answer:
Let's try and figure it out yearly:
So for the first year the deposits would amount to 40 * 12 = $480
Now since the interest rate is applied yearly we will assume that the interest rate will be applicable to the amount that is left after the first year of deposits
So that would be 889.98 - 480 = 409.98
409.98 * 14.99 % = 61.45
The new amount owed for the second year would be 409.98 + 61.45 = 471.43
So by the end of the second year the debt would of been wiped clean with $8.57 to spare.
So the answer would be 24 months

Answer:
8%
Step-by-step explanation:
560 interest/7 years=80 interest per year
1000xinterest rate=80
interest rate = 80/1000
Interest rate is 8%
Answer: It's (3,-2)
Step-by-step explanation:
A.) Since there are no restrictions as to the dimensions of the candle except that their volumes must equal 1 cubic foot and that each must be a cylinder, we have the freedom to decide the candles' dimensions.
I decided to have the candles equal in volume. So, 1 cubic foot divided by 8 gives us 0.125 cubic foot, 216 in cubic inches.
With each candle having a volume of 216 cubic inches, I assign a radius to each: 0.5 in, 1.0 in, 1.5 in, 2.0 in, 2.5 in, 3.0 in, 3.5 in, and 4.0 in. Then, using the formula of the volume of a cylinder, which is:
V=pi(r^2)(h)
we then solve the corresponding height per candle. Let us let the value of pi be 3.14.
Hence, we will have the following heights (expressed to the nearest hundredths) for each of the radius: for
r=2.5 in: h=11.01 in
r=3.0 in: h= 7.64 in
r=3.5 in: h= 5.62 in
r=4.0 in: h= 4.30 in
r=4.5 in: h= 3.40 in
r=5.0 in: h= 2.75 in
r=5.5 in: h= 2.27 in
r=6.0 in: h= 1.91 in
b. each candle should sell for $15.00 each
($20+$100)/8=$15.00
c. yes, because the candles are priced according to the volume of wax used to make them, which in this case, is just the same for all sizes
