Question: Shondra has 7 fewer plants than Toni. Toni has 60% more plants than Frederick. If Frederick has 10 plants, how many plants does Shondra have?
Give me a solution to this problem
Answer: 
Toni has 10 * 0.60 = 6 more plants than Frederick
Toni has a total of 10 + 6 = 16 plants
Shondra has 16 - 7 = 9 plants.
