My Rotary Club is having a geranium sale. They are selling for $3.25 each or 3 plants for $9.00.

The spreadsheet will show the customer's name and quantity of each color of geranium purchased. There are 4 varieties. One cell calculates the total plants purchased and another the total due.

If a customer purchases 11 plants, what would the formula be to calculate the amount due?

Thanks,

Joe
