Answer: a very straight forward b 2 4 and 6 c 9
Step-by-step explanation:
No, Perry is not using the correct ratio, because 15:17 is not equivalent to 5:7
15 divided by 3 is indeed 5 but divided 17 by 3 does not give you 7, nor a whole number.
I hope this helps.
15(1.03)^x > 25
(1.03)x > 25/15
x ln 1.03 > ln (25/15)
x > 17.28
So the required year will be 2018
