Answer:

Depends on whether it is the simple interest or compound interest.

If simple interest :  the principal is : 22, 904.76

if compound interest :  21, 546.07

Step-by-step explanation:

If it is a simple interest  then:

     interest = principal * period * rate of interest

    SI = P * n * r

     3, 607.50 = principal * 4.50 * 3.50/100

     Principal = 22,  904.76

If it is the compound interest then:

     CI = P * ( 1 + r/100)ⁿ

     3,607.50 = P * (1 + 4.50/100)⁴°⁵⁰ - P

      P = 3,607.50 / [ 1.045⁴°⁵⁰ - 1 ]

         = 21, 546.07
