Gina's snake eats one mouse every 4 weeks. How many mice will it eat in a decade?
Thoughts? Step-by-step reasoning:
First find the number of mice the snake eats each year: 52 weeks / year / 4 weeks / mouse = 13 mice / year. Then multiply the number of mice the snake eats per year by the number of years per decade to find the number of mice it eats per decade: 13 mice / year * 10 years / decade = 130 mice / decade.
Thus, the answer is 130.
