Answer :
Answer:
(1)500 sheets for $ 4.29, Unit Price=$0.00858 per sheet
(2)12 ounces for $0.95, Unit Price = $1.27 per pound
Explanation:
Part 1
[tex]\begin{gathered} 100\text{ sheets for \$0.99} \\ \text{Unit Price=}\frac{\text{0.99}}{100}=\$0.0099\text{ per sheet} \\ 500\text{ sheets for \$4.29} \\ \text{Unit Price=}\frac{\text{4.29}}{500}=\$0.00858\text{ per sheet} \end{gathered}[/tex]The unit price for 500 sheets for $4.29 is lower, therefore, it is the best buy.
Part 2
1 pound for $ 1.29
[tex]\begin{gathered} \text{Unit Price=}\frac{\$1.29}{1} \\ =\$1.29\text{ per pound} \end{gathered}[/tex]12 ounces for $ 0.95
To compare, both must be in the same unit.
[tex]\begin{gathered} 16\text{ ounces = 1 pound} \\ 12\text{ ounces = 12}\times\frac{1}{16}=0.75\text{ pounds} \end{gathered}[/tex]Therefore, the unit price:
[tex]\begin{gathered} \text{Unit Price=}\frac{\$0.95}{0.75} \\ =\$1.27\text{ per pound} \end{gathered}[/tex]Therefore, 12 ounces for $0.95 is a better buy.
