Jen and Melinda were on the phone planning a party. When Melinda's younger sister picked up the phone and heard Jen say, "Bring all your CD's."
Melinda
answered, "OK, but you have twice as many of them as I have."
Jen replied, "I know, but you have 'The Cure' and I don't. I'll tell Misty to bring all her CD's too."
Melinda added, "Misty has 3 fewer than I have."
Suddenly they heard Melinda's sister Vicki say, "Can I go to the party too?"
"NO!" yelled Melinda.
"Wait," said Jen, "Let's give her a test and if she gets the correct answer, she can come to the party."
"What do you have in mind?" Melinda questioned.
"Well, we will have 61 CD's at the party. If Vicki can guess how many of the CD's are mine she can come," said Jen.
"OK," said Melinda.
What guess would have allowed Vicki to attend
the party?
