After we finished work on the deck we drove around different places selling watermelons out of the back of Norm 's truck . We got about 150 for $ 100 and sold them 1 for $ 3 or 2 for $ 5 . We figured it 'd be an evening of easy money . Only we only sold about 20 so we did n't even make back our investment .
What 's the maximum amount of money we have made from selling the watermelons ?
- We made 50 dollars at most .
 - We made 40 dollars at most .
 - We made 45 dollars at most .
 - None of the above choices .
