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?
answer: Toni has 10 * 0.60 = <<10*0.60=6>>6 more plants than Frederick
  Toni has a total of 10 + 6 = <<10+6=16>>16 plants
  Shondra has 16 - 7 = <<16-7=9>>9 plants.
