Anonymous asked:During a one-cent sale, a shopper pays the regular price for a bottle of vegetable oil and pays $0.01 for a second bottle. If the regular price of the vegetable oil is $1.89, how much per bottle does the shopper save y buying two bottles at this sale?
OK. First, figure out how much the shopper paid. The first bottle cost $1.89. The second one cost $0.01. That’s a total of $1.90.
Usually, the bottles would have cost 2($1.89) = $3.78. So that’s a savings of $1.88.
We’re asked for the PER BOTTLE savings, so we need to divide that by 2. $1.88/2 = $0.94. That’s our answer.
