The Percent by which the store increased the price per dozen eggs
[tex]\frac{\text{Selling price}-\text{Cost price}}{Cost Price}\times 100\\\\ =\frac{3.50-0.432}{0.432}\times 100\\\\=\frac{3.068}{0.432}\times 100\\\\ 7.1018 \times 100=710.18[/tex]
So, the percent by which the store increased the price per dozen eggs=710.18%(Approximately)
Profit percentage is used to calculate the amount of gain made during selling or transaction. It can be calculated by:
[tex]\dfrac{\text{Selling Price - {Cost Price}}} {\text{Cost Price}} \times 100[/tex]
The profit percent made by the storekeeper per dozen eggs is 710.18%.
Given that,
Cost of bucket eggs = $16.20
Number of eggs in the bucket = 450 eggs
The selling price of dozen eggs = $3.50
The cost price of 12 or a dozen eggs will be:
[tex]\dfrac{16.20 \times 12}{450}[/tex] = 0.432
The profit percent made by the storekeeper will be:
[tex]\begin{aligned}&=\dfrac{\text{Selling Price - {Cost Price}}} {\text{Cost Price}} \times 100\\\\&=\dfrac{3.50 - 0.432} {0.432} \times 100\\\\&=\dfrac {3.068}{0.432}\times 100\\\\&=7.1018 \times 100 = 710 .1 \end{aligned}[/tex]
