Jenny and dan have $330 altogether. jenny has $60 more than dan. how much should jenny take from dan so that she has twice as much as dan?

To find out how much they currently have, divide the 330 by 2. You should get 165. Since she has $60 more than him, divide that by two and subtract that thirty from one of the 165 to get $135 and add $30 to the other 165 to get $195. So currently Jenny has $195 while Dan has $135. To find how much Jenny would need to take from Dan, in order to have twice as much as him divide the 330 by three. (You divide by three cause Dan has one part and Jenny has double that which means she has two parts and two plus one is three.) You should get 110. Since Dan is only going to have 110 and Jenny is going to have 220 get the 135 and subtract 110 from it. You get $25 which is the amount Jenny has to take from Dan in order to have double the amount of money he has.
