An ice cream store sells ice cream in a cup or in a cone. it sells 7 cones for every 3 cups of ice cream it sells. if 220 people buy ice cream at the store today, how may cones would the store sell?

I m not sure of my answer but i think its correct...

7 cones/ 3 cups of ice cream.

The nearest multiple of 3 to 220 is 219

 one cone per cup = 7/3 ( 7 cones for 3 cups )

Total no of cups sold = 219*  One cone per cup
                                     = 219* 7/3 
                                     = 511 cones

Therefore, the number of cones the store would sell is 511 cones.

3cups+7cones=10 altogether
22x10= 220 customers
22x7=154
3x22=66
So 154 cones
