Question

An ice cream store with 12 different flavors sells one and two-scoop ice cream cones. A boy sitting outside the store counted 11 people with ice cream cones and a total of 15 scoops of ice cream. How many one scoop cones were sold?

Answer 1

Let the number of one scoop ice cream sold = x

Let the number of two-scoop ice cream sold = y

A total of 15 scoops of ice cream were sold, therefore:

`x+y=15`
