TIMS Task

  1. Kim will have to save for 7 weeks, which is longer than a month.

One possible strategy for solving this problem is to skip count by sevens:

Weeks:

1 2 3 4 5 6 7
$7 $14 $21 $28 $35 $42 $49
  1. $100; 10 × 10 weeks = $100

J. Kim's Savings

  1. Kim earns $7 each week mowing lawns. She wants to buy jeans that cost $45. The tax will be $3. How long will she have to save to buy the jeans?

    Will she have to save longer than a month? Why or why not?
  2. Lily earns $10 each week babysitting. How much money will she earn in 10 weeks?
