Answer:
Kelsey can buy 9 books.
Step-by-step explanation:
If Kelsey wants to buy as much books as possible with 30$, multiply 3$ by 9 (books) which is 27$.
30$-27$ is 3$ so she will have 3$ extra dollars to use for shipping. 2$ is the price for shipping so she will have an extra dollar.

0
However, if you are saying one multiple of 3 involves exponential powers, Then 3^4 is 81 and 4^3 is 64
4^3 = 64
64 - 81 = -17
Side x side=area of a square
s^2=169
s= square root of 169
s=13
D.
Hope this helps.
