Use number sense duane and mick are saving their money to build a tree house. duane adds $5. ti their piggy bank every other week mick adds $2.every week. so far they have saved $45.how many weeks have they been saving money?

All you have to do for this is count every week the amount of money Duane and Mick earn.  We'll start with $5 from Duane and $2 from Mick on the first week. The second week, only Mick gives $2, and so on. To earn $45, the two boys will have worked 10 weeks. I hope this helped! :)
