63x+45x   = 108x

You just multiply 3x by 21 and 15 to get 63x and 45x. You then add the like terms to get 108x.

Determine the final amount after 20 years with a 5% annual interest rate if:you invest $10 000 in an account that earns compound
alekssr [168]

Answer:

$27,014.85

Step-by-step explanation:

We're gonna use the compound interest formula: P = A(1 + r/n)^nt

P = final amount

A = starting amount (10,000)

r = rate (0.05)

n = times applied (4 since it's quarterly)

t = years (20)

P = 10,000(1 + 0.05/4)^4*20

P = 10,000(1.0125)^80

P = 27,014.84940753337

Round it to just 27,014.85

P=A/(1+i/m)^mn

P=(20,000)÷(1+0.09÷12)^(12×4)
P=13,972.28
