Jenny,Bob and Paul share a sum of money. Jenny received 2/5 of the money, Bob received 1/4 of the money and Paul received the rest of the money. If Paul received $1.50 more than Bob, how much more money did Jenny receive than Paul?

If there were x dollars to share, then

j+b+p = x
j = 2/3 x
b = 1/4 x
p = 1.50+b
