The kids in mrs. b's class did a survey about their favorite flavors of ice cream. one-fourth of the class likes strawberry the best. one-half of the class likes chocolate the best. the rest of the class, 7 kids, said vanilla is their favorite ice cream flavor. how many kids are in mrs. b's class?

28 Students

Step-by-step explanation:

Let's break down all of our variables.

likes strawberry

likes chocolate

7 likes vanilla

First we need to combine the number of students that like strawberry and chocolate.

This then tells us that the 7 kids that like vanilla are the remaining of the class.

Let's use ratio to find out how many students there are in total.

Let x = number of student in Mrs. B's class.

We need to multiply 4 to 7 and x to 1.

So that leave us with:

x = 28

There are 28 students total in Mrs. B's class.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
