Paul is collecting license plates from different states. He has plates from 40 different states. For each percentage point of total US states that he has, his parents will give him $2. How much does he earn from them? Think carefully first, then make a decision:
The proportion of plates that he has out of total states is .8 because 40 / 50 = .8. He has 80% of the plates because .8 x 100 = 80. He makes $160 because 80 x 2 = 160. So, the answer is 160.
