✔ 最佳答案
The interest for the 1st year= $105,000 * 7% = $7,350
The amount owing at the end of the 1st year = 105000 + 7350 = $112,350
The interest for the 2nd year
= $112,350 * 7%
= $7,864.5
The amount owing at the end of the 2nd year = 112350 + 7864.5 = $120,214.5
The interest for the 3rd year
= $120,214.5 * 7%
= $8415.015
The amount owing at the end of the 3rd year = 120,214.5 + 8415.015
= $128,629.515
