Answer:

R = 3.057% per year

Step-by-step explanation:

This is a compound interest question

From the question, we have the following information

P = Principal = $1,725.95.

A = Amount after 25 years = $3,703.05

T = Time = 25 years

n = Compounding frequency = compounded monthly = 12

r = interest rate = ???

The formula to calculate the interest rate in a compound interest question =

r = n[(A/P)^1/nt - 1]

r = 12[($3,703.05/$1,725.95)^1/12× 25 - 1]

r = 3.057%

Therefore, the interest rate on the account is 3.057%

Anuta_ua [19.1K]

Answer:

$113.4

Step-by-step explanation:

If it is 40% off then it is 100-40 = 60% of original price.

So we do 180$ * .6 = $108 before tax.

To add on tax we do: 100 + 5 = 105% of that price.

So we do: $108 * 1.05 = $113.4 after discount and tax.
