Sonny's Allowance: Learning to Choose Wisely in Bunnyland

Sonny is a small rabbit. He has an allowance jar (\u96f6\u94b1\u70df). This is where he keeps his carrots. In Bunnyland, carrots are money. Every Saturday, Sonny gets three carrots for his allowance. Sonny loves Saturdays. "I want to buy everything!" he says. "Everything?" Sonny\u2019s mom asks. "Yes. Everything! When I see a toy plane, I want to buy it! When I see a basketball, I want to buy it! When I see a bouncy castle (\u586b\u6c14\u57ce\u5821), I want to buy it!" "One problem, Sonny. You only get three carrots a week. So you can\u2019t buy everything." Mom says, "You need to choose (\u9009\u62e9) and see what\u2019s really useful to you." But Sonny thinks, "I have three carrots. I want three things. So why do I need to choose?" Mom says, "Well, let\u2019s see. The toy plane costs (\u82b1\u8d39) you two carrots. The basketball costs you three carrots. And you need 100 carrots for the bouncy castle." "What? 100 carrots? Oh, no\u2026" "And the toy? You have lots of toys at home." "Yeah. You\u2019re right. So what can I buy with my three carrots?" He thinks for a while, "I know! I\u2019ll buy the basketball!" Mom says, "Great, Sonny! Now you know how to use money in the right way."\n\u9605\u8bfb\u77ed\u6587\uff0c\u56de\u7b54\u4ee5\u4e0b\u95ee\u9898\uff0c\u6bcf\u9898\u7b54\u6848\u4e0d\u5f97\u8d85\u8fc78\u4e2a\u8bcd\u3002\n\n4.What does Sonny buy at last\u5185\u5bb9\uff1aSonny buys the basketball.
