Solutions
Annie puts $10 into a vacation jar each week and we need to find out <span>how much will she have saved by the end of the year. To solve the problem first we have to find out how many days there are in a year and convert them into weeks.
Days in a year = 365
To find weeks divide by 7 since a week consists of 7 days.
365 </span>÷ 7 = 52
<span>
1 year has 52 weeks
our next step is to multiply 52 by 10.
52 x 10 = 520
By the end of the year she would have saved 520 dollars. </span><span />
