A: He has given out 120 tickets because 15 x 8 = 120. He has 16 days left to had out tickets because 31 - 15 = 16. He has to give out 80 more because 200 - 120 = 80. He has to give out 5 a day because 80 / 16 = 5. The answer is 5.

Q: Mo is buying valentine's day cards for the class. There are 30 students and he wants to give a Valentine to 60% of them. They cost $2 each. If he has $40, what percentage of his money will he spend on Valentine?
A: He needs 18 valentine's cards because 30 x .6 = 18. He will spend $36 on these because 18 x 2 = 36. The proportion of his income spent is .9 because 36 / 40 = .9. This is 90% of his income because .9 x 100 = 90. The answer is 90.
