Brand B is cheaper by $0.02 per fluid ounce. #### Explanation: As a rule, "of" means multiply, and "per" means divide. We have been asked for "cost, in dollars, per fluid ounces". We need to divide cost, in dollars, by fluid ounces. Brand A: $1.28 / 8 = $0.16 per fluid ounce. Brand B: $1.68 / 12 = $0.14 per fluid ounce. The difference between brand A and brand B is$0.02 per fluid ounce, with brand B being cheaper.
