To calculate the weekly investment needed, we can use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the desired amount, P is the principal (initial investment), r is the interest rate, n is the number of times interest is compounded per year, and t is the number of years.
In this case, the desired amount is $6,000,000, the interest rate is 5.9%, and the investment is compounded weekly. We need to solve for P, the weekly investment.
Let's plug in the values into the formula:
$6,000,000 = P(1 + 0.059/52)^(52*9)
Now, we can solve for P:
P = $6,000,000 / [(1 + 0.059/52)^(52*9)]
Calculating this will give us the weekly investment amount that the company needs to make in order to reach their goal.
