To break even, the total revenue from selling watches should cover both the variable costs (labor and materials per watch) and the fixed costs. Let's calculate the breakeven point:
Let's represent the number of watches to be produced and sold each day as "x."
Total Cost = Total Fixed Cost + (Cost per Watch * Number of Watches)
Total Revenue = Price per Watch * Number of Watches
For break-even, Total Cost = Total Revenue:
Total Fixed Cost + (Cost per Watch * x) = Price per Watch * x
Now, plug in the given values:
$2000 + ($15 * x) = $20 * x
Now, let's solve for "x" (the number of watches to be produced and sold each day):
$2000 = $20x - $15x
$2000 = $5x
x = $2000 / $5
x = 400
Therefore, the watchmaker should produce and sell 400 watches each day to guarantee breaking even. At this production level, the total revenue from selling 400 watches at $20 each will be sufficient to cover the total variable costs ($15 per watch) and the fixed costs ($2000 per day).
