To find the cost of one organic apple at the grocery store, you can first calculate the markup and then add it to the original cost.
Markup Percentage: The grocery store marks up the cost by 18%, which means the markup percentage is 18%.
Markup Amount: To find the markup amount, multiply the original cost ($0.75) by the markup percentage (18% or 0.18):
Markup Amount = $0.75 * 0.18 = $0.135
Total Cost: To find the total cost of one organic apple, add the markup amount to the original cost:
Total Cost = Original Cost + Markup Amount
Total Cost = $0.75 + $0.135
Total Cost = $0.885
To the nearest cent, one organic apple at the grocery store will cost approximately $0.89.
