1. 10 weeks= $50                                       1. 10 weeks= $40

2. 10 weeks= $50                                      2. 10 weeks= $40

3. 10 weeks= $50                                      3.  10 weeks= $40

4. 10 weeks= $50                                      4. 10 weeks= $40

5. 10 weeks= $50                                      5. 10 weeks= $40

6. 10 weeks= $50                                      6. 10 weeks= $40

7. 10 weeks= $50                                       7. 10 weeks= $40

8. 10 weeks= $50                                       8. 10 weeks= $40
