Answer 15

Not quite, almost!!! For this one, you need to figure out the amount he gets per year first. So, if he got $225 for 5 years...$225/5=$45. He got $45 in interest per year. And really the fastest way to do this one is plug in your answer choices. 750 times what gives you the $45?
750x5%= 37.45. Nope, doesn't=45.
750x5.5%= 41.25. Nope, doesn't=45.
750x6%= 45. Yes, ='s 45.
750x6.5%= 48.75. Nope, doesn't=45.

Answer 16

ok so 6

Answer 17

Yes! :))
