First Week = 10 pennies
Second Week = 20 pennies
Third Week = 30 pennies
Fourth Week = 40 pennies
Fifth Week = 50 pennies
Sixth Week = 60 pennies

Amy will have:
10 + 20 + 30 + 40 + 50 + 60 = 210 pennies

问题问的是 how many pennies will Amy have (Amy 将会有多少分钱)? 也就是问 Amy 总共会存下多少分钱。所以这一题的答案是 210 分钱。

如果问题是 How many pennies will Amy save the sixth week (Amy 在第6周存下多少分钱) ? 答案才会是 60 分钱。
