Aaron works 3 1/2
hours every Saturday at a rate of $7.25 per hour. He is paid every four weeks. If his boss gives him a $1.00 raise, how much will Aaron be paid in his next paycheck?
Aaron works 3 1/2 hours every Saturday, so he works a total of 3.5 * 52 = <<3.5*52=182>>182 hours in a year.
At a rate of $7.25 per hour, Aaron earned 182 * 7.25 = $<<182*7.25=1319.5>>1319.5 in a year.
Since Aaron is paid every four weeks, he is paid 52 / 4 = <<52/4=13>>13 times in a year.
Therefore, Aaron earns 1319.5 / 13 = $<<1319.5/13=101.50>>101.50 every time he is paid.
If Aaron receives a raise of $1.00, he will now earn 7.25 + 1 = <<7.25+1=8.25>>8.25 per hour.
So Aaron will now earn 8.25 * 182 = $<<8.25*182=1501.5>>1501.5 in a year.
Thus, in his next paycheck, Aaron will receive 1501.5 / 13 = $<<1501.5/13=115.50>>115.50. Answer: \boxed{115.50}.
