Ok, so if it has increased over three years by twelve percent, take .12 (12% in decimal form) and multiply it by 750 to get 90. Take 90 and multiply it by 3 to get 270. 270 is how much the value has increased over 3 years. So then just add 270 to 750 to get your answer of 1020. 1020 is how much the stock is worth after 3 years increasing at 12%. Just follow the same steps for 2% and 5% as I showed you with the 12%.
As everyone says (lol) hope this helps :D
