Calculation:
The first rate of crackers is 20 ounces for $2.39. In this case, the number of units is 20. So, to find the unit price, we divide the given price by the number of ounces of crackers. In fractional form, $\frac{\mathrm{}2.39}{20ounces}$. Let's divide 2.39 by $20:2.39÷20=0.1195$ Rounding 0.1195 to 3 decimal places, we get 0.120. Thus, unit price is $\frac{\mathrm{}0.120}{1ounce}$. The above unit price can be written as$0.120/ounce which is read as $0.120 per ounce. The second rate of crackers is 8 ounces for$0.99. In this case, the number of units is 8.
So, to find the unit price, we divide the given price by the number of ounces of crackers.
In fractional form,
Let's divide 0.99 by $8:0.99÷8=0.12375$
Rounding 0.12375 to 3 decimal places, we get 0.124
Thus, unit price is
The above unit price can be written as $0.124/ounce which is read as$0.124 per ounce.
Since the 20 ounce package has a cheaper price per ounce, it is the better buy.
Final solution:
The unit price of 20 ounces for $2.39=0.120/ounce$
The unit price of 8 ounces for $0.99=0.124/ounce$
The 20 ounce package is a better buy.
