To determine which is the better buy, we need to calculate the price per bar of soap for each option.
For the first option: 12 bars for $10.00 Price per bar = Total cost / Number of bars Price per bar = $10.00 / 12 bars Price per bar = $0.83 (rounded to two decimal places)
For the second option: 5 bars for $4.00 Price per bar = Total cost / Number of bars Price per bar = $4.00 / 5 bars Price per bar = $0.80 (rounded to two decimal places)
Comparing the two prices per bar: - 12 bars for $10.00 is $0.83 per bar - 5 bars for $4.00 is $0.80 per bar
Therefore, the 5 bars of soap for $4.00 is the better buy since the price per bar (at $0.80) is less than the price per bar of the 12 bars for $10.00 (at $0.83).
