k=2
Step-by-step explanation:
3^k*2 * 3^-k+2 = 81
Factor out 81 to be : 3^4

k*2 - k+2 = 4
k^2 - 2k = 4
Simplify : k+2 = 4
<u> - 2 - 2</u>
k = 2
If 2/3 is equal to 1 batch of muffins

multiply the numerator by the numerator and the denominator by the denominator
2/3 *3/1 = 6/3 or simplified to...
2 cups of milk
193.09x15/100=28.9635
193.09-28.9635=164.1265
164.1265x5/100=8.206325
164.1265+8.206325=172.332825
