Joelle has 5 orchids and 4 African daisies on her balcony.  If the orchids have 5 petals and daisies have 10 petals, how many more petals do the daisies have compared to the orchids?
What is the solution?
The number of petals on orchids is 5 x 5 = 25.
The number of petals on daisies is 4 x 10 = 40.
Daisy petals outnumber orchid petals by 40 - 25 = 15.
