The <u>correct answer</u> is:
$475
Explanation:
Jake earns $24,700 per year. If he spends no more than one week's pay on rent per month, we need to know how much of this salary he earns each week. There are 52 weeks in a year, so we divide 24700 by 52:
24700÷52 = 475.
Jake earns $475 each week, so he should spend no more than this in rent.
