which is the better buy? 2 - kilogram bag of sugar for $1.93 9 - kilogram bag of sugar for $8.35
Answer
Explanation:
Step1: Calculate unit - price of 2 - kg bag
To find the unit - price (price per kilogram), divide the total price by the number of kilograms. For the 2 - kilogram bag, the unit - price $u_1$ is $u_1=\frac{1.93}{2}$. $u_1 = 0.965$ dollars per kilogram.
Step2: Calculate unit - price of 9 - kg bag
For the 9 - kilogram bag, the unit - price $u_2$ is $u_2=\frac{8.35}{9}$. $u_2\approx0.928$ dollars per kilogram.
Step3: Compare unit - prices
Since $0.928<0.965$, the 9 - kilogram bag has a lower unit - price.
Answer:
The 9 - kilogram bag of sugar for $8.35 is the better buy.
