Final answer:
The percent markup for buying individual avocados compared to buying them in a pack is approximately 29.7%.
Step-by-step explanation:
The question asks about the percent markup when purchasing avocados individually versus in a pack. Initially, let's find the cost per avocado when bought in a pack. This cost is $11.10 per package of 6 avocados, which amounts to $11.10 / 6 = $1.85 per avocado.
To find the percent markup, we compare the individual avocado price to the package price per avocado. The individual price is $2.40 compared to $1.85 when bought in a pack. The difference is $2.40 - $1.85 = $0.55.
The percent markup is calculated as: ($0.55 markup / $1.85 original price) × 100 = 29.73%, which can be rounded to approximately 29.7%.
