One safe investment pays 8% per year, and a more risky investment pays 12% per year.

Mathematics

Principal = 109,000

Return - 9,920

Return = (principal x rate x time)/100

X = the amount invested at 12%

Then 102000- x = the amount invested at 8%

9920 = (x*12)/100 + (109000-x*8)100

x = 30,000

a) 30,000 is invested at 12%

79,000 is invested at 8%

b) The 12% investment is riskier so if all the money was in that account the investor could lose all his money.

Purchase price (PV)= $800

Decrease value (d)= 1.5% per year

Number of periods (n)= 12 years

<u>To calculate the value of the card after 12 years, we need to use the following formula:</u>
