On Sunday, Jan. 7, 2007, Rob has $5 he saved from his birthday, and he receives his first allowance payment of $35. He will continue to receive a allowance payment every Sunday. However, starting Jan. 7, 2007, Rob is also responsible for paying for his five lunches each week at $3 per lunch and his weekly Saturday movie that costs $9.50. If Rob always adds the remainder of his allowances each week to his current savings, after how many total allowance payments will he have enough money to pay for the $50 CD player he wants and still be able to cover his expenses for the rest of that week?

He starts week 1 with 40 each week he has 24.5 in obligations and is left with 15.5

each subsequent week adds 35 and subtracts 24.5 for a net of 10.5 increase at the end of the week

Week 2 end he will have 26

week 3 end he will have 36.5 still not enough to buy $50 CD set

Week 4 end he will have 47 Getting close!

Week 5 end he will have 57.5 Made it ! At the beginning of week 5 he can buy his CD set and still cover his expenses for the rest of the week !

He will hve received 5 $35 allowances
