These three bottles of aspirin were bought over the past couple of years at a local dollar store. During that that time, the price has remained the same - one dollar per bottle. A closer look at the labels tells a different story. The quantity in each bottle has gone down.
Some numbers:
Price per aspirin:
$1.00 for 140 aspirin = $$0.007143 = 0.715 cents each
$1.00 for 125 aspirin = $0.008 = 0.8 cents each
$1.00 for 100 aspirin = $0.01 = 1 cents each
If the quantity remained the same but the price went up:
140 aspirin (at 140 price per) = $1.00
140 aspirin (at 125 price per) = $1.12
140 aspirin (at 100 price per) = $1.40
100 aspirin (at 140 price per) = $0.72
100 aspirin (at 125 price per) = $0.80
100 aspirin (at 100 price per) = $1.00
