I believe George will have 249.75 dollars.
If he earns 9.5% annually, you would have to multiple .095 which is 9.5% by 150 to get 14.25. Once you have that you need to multiply it by 7 for the 7 years that it’s in the account to get 99.75, next add that to 150 to get the answer
150 x .095 = 14.25
14.25 x 7 = 99.75
99.75 + 150 = 249.75
Hope it’s helpful:/
