Kirsty collects small models of animals. The last time she bought some, each one cost $0.45. She saves enough to buy 30 models, but when she goes to the shop, she finds out that the price had increased to $0.50. How many models can she buy now?
Kirsty has 0.45 × 30 = $<T>multiply(0.45, 30)=13.5 to spare to buy her models.
She can only buy 13.50 ÷ 0.50 = <T>divide(13.5, 0.5)=27.0 models as the price of each individual model has increased.
