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, $\frac{$ 2.39}{20 o u n c e s}$ .
Let's divide 2.39 by $20 : 2.39 \div 20 = 0.1195$
Rounding 0.1195 to 3 decimal places, we get 0.120.
Thus, unit price is $\frac{$ 0.120}{1 o u n c e}$ .
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, $\frac{$ 0.99}{8 o u n c e s}$
Let's divide 0.99 by $8 : 0.99 \div 8 = 0.12375$
Rounding 0.12375 to 3 decimal places, we get 0.124
Thus, unit price is $\frac{$ 0.124}{1 o u n c e}$
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 $$ 2.39 = $ 0.120 / o u n c e$
The unit price of 8 ounces for $$ 0.99 = $ 0.124 / o u n c e$
The 20 ounce package is a better buy.
