Answer: Price per Bag * Number of Bags = $1 * x = R(x)
To find the break-even point for the popcorn business, you need to find the number of bags of popcorn that need to be sold in order to cover the total cost, which includes the fixed cost of the machine and the variable cost of the consumables.
Calculate the cost per bag of popcorn for the consumables:
$15 for every 100 bags of popcorn ÷ 100 bags = $0.15 per bag.
Write an equation for the total cost as a function of the number of bags of popcorn made:
Total Cost = Variable Cost + Fixed Cost
Variable Cost = $0.15 * Number of Bags
Total Cost = $0.15 * Number of Bags + $450
Let C(x) represent the total cost where x is the number of bags of popcorn.
C(x) = $0.15 * x + $450
Write an equation for the revenue as a function of the number of bags of popcorn sold:
Revenue = Price per Bag * Number of Bags
Price per Bag = $1
Revenue = $1 * Number of Bags
Let R(x) represent the revenue where x is the number of bags of popcorn.
R(x) = $1 * x
Set the revenue equation equal to the total cost equation and solve for x, the number of bags of popcorn that need to be sold to reach the break-even point:
R(x) = C(x)
$1 * x = $0.15 * x + $450
$0.85 * x = $450
x = $450 ÷ $0.85 = 529 bags
Therefore, the business club needs to sell 529 bags of popcorn in order to reach the break-even point and cover their costs.
