Question

4 ice cream cones cost $10.00. At this rate, how much do 3 ice cream cones cost?

Answer 1

$7.50

Explanation:

4c=10

4c/4=10/4

c=2.5

3c=x

3(2.5)=x

7.5=x

Answer 2

Since you dont know the unknown money per cone we make it an equation:

4c(unknown money per cone) = $10

Let's divide both sides by 4

C = 2.50, now we found out the cost of 1 cone.

Since there are 3 cones we multiply by 3,

2.50 x 3 = $7.50
