$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

step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
