问题
Grandma sent Johnny some money for his birthday, Johnny spent all of it in five stores.In each store, he spent $1.00 more than half of what he had when he came in.How much money did he get from grandma?
选项
A、7.5
B、30
C、46
D、62
答案
D
解析
Jonny生日时,奶奶给了他一些零花钱,Jonny在5个商店将这些钱花完了。在每家商店花的钱都比进店时的一半还多1元。那么奶奶给了Jonny多少零花钱?做这道题时,解题要点就是—— Johnny 最后一次花的钱就是他身上所剩的钱,假设他最后一次剩余X块钱。那么我们可以列出方程式:X/2+1 = X,这样就能解出X=2,依次往前类推,可以得出第一次的钱是 62块。
