Final answer:
To determine the total cost of a $47.00 tie with a 4.5% markup, convert the markup to a decimal, calculate the additional cost due to the markup, and then add it to the original price, resulting in $49.12, which is closest to $49.13.
Step-by-step explanation:
The question asks to calculate the total cost of a $47.00 tie with a 4.5% markup. To find the markup amount, multiply the original price by the markup percentage, and then add this to the original price to get the total cost.
Step 1: Convert the markup percentage to a decimal: 4.5% = 0.045
Step 2: Calculate the markup amount: $47.00 × 0.045 = $2.115
Step 3: Add the markup to the original price to find the total cost: $47.00 + $2.115 = $49.115
Rounding the result to the nearest cent gives us $49.12, which is not an option provided, but it is closest to choice b) $49.13.
