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)
