  • The total interest was $900

[tex]\large\tt\green{Step-by-step \: explanation}[/tex]

Step 1:

Put the numbers in the formula and do the arithmetic.

  • I = P × R × T
  • I = $4500 × 5% × 4

Step 2:

Rename 5% into decimal

  • I = P × R × T
  • I = $4500 × 0.05 × 4

Step 3:

Solve the problem with the full solution.

  • I = P × R × T
  • I = $4500 × 5% × 4
  • I = $4500 × 0.05 × 4
  • I = $ 900

Therefore, the total interest was $900
