How much will Billy Dan and Betty Lou have to invest each year to purchase their dream home at the end of 12 years? Assume an interest rate of 10 percent.

Use the following formula to calculate the amount of yearly investment.

Cost to purchase the house = $247,000

Interest rate = 10%

Numbers of years = 12 years

Annual investment = ?

Placing values in the formula

$247,000 = Annual investment x ( 1 + 10% )^12 ) - 1 ) / 10%

$247,000 = Annual investment x 21.384284
