To be able to buy a new computer, Salma decides to save for 4 years. She opens a savings account with $600. The account pays simple interest at an annual rate of 5%. She doesn't make any more deposits.
5% of 600 is 30, then you multiply the 30 by the 4 years which gives you 120. then you add the original 600 with the 5 person from the four years which is 120 that comes to 720. so 720 is how much is in salma's account after 4 years.
