Five friends agree to save money for a graduation road trip. They decide that
each of them will put $0.25 in the fund on the first day of May, $0.50 on the
second day, $0.75 on the third day, and so on. At the end of May, there will be
$_ in their fund. (Hint: There are 31 days in May.)
First you have to figure out the amount one of them would add which is $124. You would do this by adding .25+.50+.75+1 ect. Then once you know how much one of them would add you do 124(5) and get $620.
