GalinKa [24]

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

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)

There were 200 people who voted at the Town council meeting all these people 40% voted for a new basketball court in the park ho
galben [10]

Answer:

120 people voted against building the new basketball court.

Step-by-step explanation:

if you divide 200 by 100 then you know how many people equal 1 percent of the 200. knowing that for every 2 people they are equal to 1 percent. so if you do 100 -40 you get 60. the 100 represents the 100 percent and you subtract 40 because these are the people who are voting for the basketball court. The 60 represents the percent of people who are voting against building the basketball court. then you multiply 60 by 2 and you get 120.
