Answer:
12 years
Explanation:
144,000.00 / 2,000.00 is 72 times that he deposited 2,000.00 in order to get 144,000.00. If he deposits once every 2 months then he would have deposited 72 months x 2. That is 144 months he took to deposit that much. 144 / 12 months in a year is 12 years. He takes 12 years to save 144,000.00.
