Bobby is selling snow cones at a stand outside his house. He is charging $1.50 per snow cone. He needs to make at least enough money to cover that cost his supplies, which were $15.25. What is the minimum number if snow cones Bobby needs to sell?
Bobby needs to make at least $15.25 to cover his supply costs.
Hence, he needs to sell at least $15.25 / $1.50 = <<15.25/1.5=10.17>>10.17 snow cones.
Since he can't sell a fraction of a snow cone, the minimum number of snow cones Bobby needs to sell is 11. Answer: \boxed{11}.
