Answer and Explanation:
The computation is shown below:
Present value of investment X is
= Annuity × [1 - 1 ÷ (1 + r)^n] ÷ r
= $4,800 × [1 - 1 / (1 + 0.06)^9] ÷ 0.06
= $4,800 * 6.801692
= $32,648.12
And,
The Present value of investment Y is
= Annuity × [1 - 1 ÷ (1 + r)^n] ÷ r
= $7,100 × [1 - 1 ÷ (1 + 0.06)^5] ÷ 0.06
= $7,100 × 4.212364
= $29,907.78
