$12000 is compounded semiannually at a rate of 7% for 22 years. find the total amount in the compound interest account

$54,520.10

Step-by-step explanation:

A = P(1 + r/n)^nt

A being the amount after interest

P being $12000

r being .07 (7% interest)

n being 2 (semiannual)

t being the amount of years its being compounded for, 22

Setting it up,

A = 12000(1 + .07/2) ^2x22

A = 12000(1.035)^44

A = 12000(4.54334159549)

A = 54520.0991459

A = 54520.10

it alot will look like this 4.4

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
