which is the better buy? 5-yard roll of fabric for $5.90 8-yard roll of fabric for $9.60
Answer
Explanation:
Step1: Calculate unit - price of 5 - yard roll
To find the unit - price of the 5 - yard roll of fabric, divide the total cost by the number of yards. Let the unit - price be $u_1$. The total cost $C_1 = 5.90$ dollars and the number of yards $y_1=5$. So, $u_1=\frac{C_1}{y_1}=\frac{5.90}{5}=1.18$ dollars per yard.
Step2: Calculate unit - price of 8 - yard roll
To find the unit - price of the 8 - yard roll of fabric, divide the total cost by the number of yards. Let the unit - price be $u_2$. The total cost $C_2 = 9.60$ dollars and the number of yards $y_2 = 8$. So, $u_2=\frac{C_2}{y_2}=\frac{9.60}{8}=1.2$ dollars per yard.
Step3: Compare unit - prices
Since $1.18<1.2$, the 5 - yard roll has a lower unit - price.
Answer:
The 5 - yard roll of fabric for $5.90 is the better buy.
