Jermaine · Answer 1

The 20% increase will be 2 more glasses of lemonade. So therefore now being 12 glasses of lemonade will be multiplied by 9hrs with result of 108 glasses - this will be the total number of glasses sold

If one glass costs $0.50 then the total costs will be

108 glasses * $0.50

answering=$54.00
