Answer:
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.
