### Instruction:
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?

### Response:
 Kirsty ana $0.45 × 30 = $<<0.45*30=13.50>>13.50 ya kuokoa kununua mifano yake.
Anaweza kununua tu 13.50 ÷ 0.50 = <<13.50/0.50=27>>27 mifano kwa kuwa bei ya kila moja imeongezeka.
