An increase is adding, not multiplying. they meant that 5 times a number is 500% of something. it would be a 400% increase as one plus four is five.

Help please I don’t know the answer
andrew-mc [135]

Answer:

$16,534.95

Step-by-step explanation:

To compute interest on loans, we use the compounded interest equation. We use the equation A=P(1+\frac{r}{n})^{nt} where

  • P is the principle or starting value
  • A is the total amount after interest and a period of time
  • r is the rate at which interest gathers as a decimal
  • t the time in years
  • n is the number of times compounded in a year.

For this problem, we know P=$8000, r=19%=0.19, t=4 years and n=2. We substitute into the formula and simplify to find the total amount A.

A=P(1+\frac{r}{n})^{nt}\\A=8000(1+\frac{0.19}{2})^{2(4)}\\A=8000(1+0.095)^{8}\\A=16,534.95
