I have a question about question 9 on the progress self test. The problem tells us that the value of the grand prize is twice the value of the other three prizes combined. The problem asks us what is the value of the grandprize. I represented the problem with the equation 3p + 2*3p=3500 where p is the value of the prize of one of the three winners. I got p=3500/9 so I multiplied 3500/9 * 3 *2 to get the value of the grandprize, $2333.33. However, when I checked the problem using the anwser key, the book used the equation x + x + x + 2x = 3500 where 2x is the value of the grandprize. 2x= 1400. If 2x is the value of the grandprize shouldn't the value of a winner be 1/3x? I do not understand how the book got their equation. Can someone explain?

The book is wrong for that question. It should be x+x+2x=3500
How do we figure out 7 and 8 on Covering The Ideas?...For 7 I did (the amount the owner pays=A)... A+A*.45=499
The closest I could get was 344.25
