Final answer:
Sanraku's historical gross profit percentage is calculated by dividing last year's gross profit ($19,485) by last year's total sales ($43,300) and multiplying by 100, resulting in approximately 44.98%.
Step-by-step explanation:
To determine Sanraku's historical gross profit percentage, we must first calculate the gross profit in dollar terms from the prior year's data provided. Gross profit is calculated by subtracting the cost of goods sold (COGS) from total sales. The formula to calculate gross profit is:
Gross Profit = Sales - Cost of Goods Sold
Using last year's figures for Sanraku, we get:
Gross Profit = $43,300 (Sales) - $23,815 (COGS)
This results in a gross profit of $19,485. To find the gross profit percentage, we divide this figure by the total sales and then multiply by 100 to get the percentage:
Gross Profit Percentage = ($19,485 / $43,300) × 100%
So, Sanraku's historical gross profit percentage is approximately 44.98%.
