7. Let's assume that one of your dreams is to invest in the purchase of an apartment in 7 years from now; you estimate that the "down payment" at that time will be $ 45,000. How much do you need to deposit at the end of each year in the next 7 years to accumulate the $ 45,000 if you can earn 8% annually compound semi-annually on your deposits? (5 points) 8. Juan wants to open an account into which he hopes to deposit the following at the beginning of each year: 1: $ 15,200; 2: $ 11,300; 4: $ 10,000.

Jaime wants to invest $ 1,200 in an account at the beginning of each of the next 15 years at a 10% per annum computed semi-annually. The total value of the account will then be left to compose for 10 additional years at an annual 12% computed annually and Jaime may receive certain amount at the end of each of the last 10 years.
