Question

Chet gets $12 per week as allowance. If he started off with $124 dollars in the bank, how many weeks would it be before he had $222?

Answer 1

9 weeks

Explanation:

If you subtract $222 dollars from $124 dollars, you would get 98. This means that Chet needs 98 more dollars to get to $222. If you multiply 12 times 8, that is 96, still not enough. This means he would have to multiply 12 times 9 which is $108. At 8 weeks he still doesn't have enough so he has to go to 9 weeks. Though he will have more than $222, he still has enough money to have $222 dollars there will just be some left over.
