1.
a. To break even, Mario needs to cover his fixed and variable costs. The contribution margin per pizza is $10 (selling price) - $4 (cost to make) = $6. The total fixed costs are $200 (rent) + $60 (advertising) + $100 (utilities) = $360. The break-even point in pizzas is $360 / $6 = 60 pizzas.
b. If he plans to sell 80 pizzas, the new selling price to break even is $360 / 80 = $4.50 per pizza.
2.
a. To make an 8% net income on sales revenue, Mario needs to sell 60 pizzas and have a net income of $10 * 0.08 = $0.80 per pizza. So, he needs to make a total net income of $0.80 * 60 = $48.
b. If he sells 80 pizzas, the new selling price to achieve an 8% net income is $4.50 + $0.80 = $5.30 per pizza.
3.
a. With reduced costs to $3.60 per pizza, the contribution margin becomes $10 - $3.60 = $6.40. To achieve an 8% net income, he needs to sell $48 / $6.40 = 7.5 pizzas, so he needs to sell 8 pizzas.
b. If he reduces advertising costs to $40 per month, the contribution margin remains $6. To achieve an 8% net income, he needs to sell $48 / $6 = 8 pizzas.
4. With free delivery and 75% of sales being delivery, Mario aims to sell 120 pizzas. The contribution margin required to achieve an 8% net income is $48 / 120 = $0.40. Since 75% are delivered, the contribution margin per delivered pizza needs to be $0.40 / 0.75 = $0.5333. To cover the delivery person's fee and achieve the desired net income, he needs to charge $10 + $0.5333 = $10.5333 per pizza.
