Hello!
Judging by the question it seems that the problem is asking for the total cost of the sweater after tax, which means you were close with your previous two guess.
8.5% in a number would be 0.085 and 100% in a number would be 1.
Thus, the answer you are looking for is 1.085!
Hope this helped!

Answer:
The term that represent the amount of money she will spend on brownies is 2b
Step-by-step explanation:
Let
c ----> the number of cones
b ----> the number of brownies
we know that
The cost of desserts can be found using the expression

where
4c ----> is the term that represent the amount of money spend in cones
2b ----> is the term that represent the amount of money spend in brownies
5 ----> is the term that represent the amount of money spend in water
therefore
The term that represent the amount of money she will spend on brownies is 2b
That means ---> the number of brownies (b) multiplied by the cost of each brownie ($2)
You have to do 1.5 times 2 and that equals something and that times 1.7
