To get the Total amount upon investment for the compound interest, plug in the value of x into the given expression bellow
A = 9,000.00(1 + x/100)^(4)
Given data
Principal = $9000
Time = 4 years
Rate = x% per annum
First, convert R as a percent to r as a decimal
r = x/100
r = x/100
Then solve the equation for A
A = P(1 + x/100)^t
A = 9,000.00(1 + x/100)^(4)
A = 9,000.00(1 + x/100)^(4)
The total amount accrued, principal plus interest, with compound interest on a principal of $9,000.00 at a rate of x% per year.
