He can spend $2.50 on each card. He starts with $13 and ends up with $5 after spending $8 on the book. Since he has 5 left and needs two cards, you divide 5 by 2 and ends up with $2.50. Hope this helps :)
For 12-15, all you really have to do is just find the square root of the numbers that need you to find the square root of and then the decimals to the fractions. If I were you, I would write the answers in decimal form when you solve for the numbers that the question is asking you, then see which one is least and start there then go to the greatest. Then I would also put the original number and not the decimal version. I'm not real sure about number 16, but I am for sure about 12-15. Hope that helped! :)
