Mr.Park purchases 45 cases of dog food.A case of 48 cans of the food costs $21.60.How much does Mr.Park pay for each can?

Question

a)If he sells each can for $1.15,how much total profit will he have made after selling all of the cans?

I do not understand the problem 

Answer 1

$21.60 / 48  = 0.45 = 45 cents per can

 

45 cases x 48 cans per case = 2160 cans

 

2160 * (1.15 - 0.45) = $1512 profit
