29. 1.08+.89+.89=2.86 they need 3 dollars
30.they need $3.34
31.each greeting card cost 35 cents
32. she does have enough money because it the total for 3 gift wraps is $5.55 which is less than $6
We have the following general rule for exponents:
![a^n\cdot a^m=a^{n+m}](https://tex.z-dn.net/?f=a%5En%5Ccdot%20a%5Em%3Da%5E%7Bn%2Bm%7D)
then, in this case we have the following:
![3^3\cdot3^{-2}=3^{3+(-2)}=3^{3-2}=3^1=3](https://tex.z-dn.net/?f=3%5E3%5Ccdot3%5E%7B-2%7D%3D3%5E%7B3%2B%28-2%29%7D%3D3%5E%7B3-2%7D%3D3%5E1%3D3)
therefore, the answer is 3
