A factory has fixed costs of \$25,000 per month. It manufactures widgets at a total manufacturing cost of \$45 per widget. They are sold at \$60. How many widgets must be sold in any given month in order to break even?
A factory has fixed costs of \$25,000 per month. It manufactures widgets at a total manufacturing cost of \$45 per widget. They are sold at \$60. How many widgets must be sold in any given month in order to break even?
Let's first represent the total costs per month:
C = 25000 + 45n, where n is the number of widgets manufactured.
The profit can be represented as 60n – C or 60n – 25000 – 45n = 15n – 25000. Now, we merely have to solve this for 0 in order to find the "break even" line.
15n – 25000 = 0 → 15n = 25000 → n = 1666.67. We must sell a whole number of widgets, so it must be 1667.

A new t-shirt has a total cost of 8 dollars for a given retailer. Its current price is \$15. If the retailer discounts the cost of the shirt by 20%, how many must it sell in order to make the same amount of profit as when it sold 300 of the shirts at the original price?

First, we must ascertain the original profit. Per shirt, the retailer made 15 – 8, or \$7. Selling 300 shirts, it made a profit of \$2,100.
The new price, discounted by 20% is equal to 80% of the original price, or 15 * 0.8 = \$12. This yields a profit of \$4 per shirt.
To ascertain the number of sales needed to make \$2,100 in profit, we must solve the following equation:
4x = 2100; x = 525 shirts

Set Original = O

then
D = (1 – 20%) x O = 0.80 x O
and Profit = \$10 so:

A shirt costs \$12 to manufacture. If the marketing and sales costs are a 75% addition to this manufacturing cost. What is the minimum price necessary for making a 50% profit?
A shirt costs \$12 to manufacture. If the marketing and sales costs are a 75% addition to this manufacturing cost. What is the minimum price necessary for making a 50% profit?
Based on the prompt, we know that the additional marketing and sales costs are 12 * 0.75 = 9; therefore, the total cost for purchase and sale is 12 + 9 = \$21. To make a 50% profit, we must make 21 * 0.5, or \$10.5, on the sale; thus the shirt must be sold for 21 + 10.5, or \$31.5.

Mary buys a car from a mean salesman who charges her 12% over the original price of a \$15,000 car. Luke buys the same car from a much nicer salesman who gives him an 8% discount off of the original price. How much more does Mary spend on the car than Luke does?

What percentage of profit is made on a product sold for \$20 if its overall production cost was \$17.50?
What percentage of profit is made on a product sold for \$20 if its overall production cost was \$17.50?
To find the profit percentage, you must first determine the amount of profit made on this transaction. If the sale price was \$20 and the production cost \$17.50, then the profit made was: 20 -17.5 = \$2.50. The profit percentage is determined by dividing the amount of profit made by the original price, or 2.5 / 17.5 = (approx.) 0.14286 or 14.29%.

Manufacturer X has a base monthly operating cost of \$30,000. It makes only one product, which costs \$5 per piece in addition to the base operational costs for the plant. These products are each sold for \$15 apiece. How many products must the company sell in order to break even in any given month?

Begin by translating your problem into an equation. What we want to ascertain is the situation when the profit equals exactly 0. The profit and loss for a given month can be summarized by the following equation:
(Total product revenue) - (Base operating costs) - (Individual costs for products) = 0
Given our data, we can rewrite this:
15 * x - 30,000 - 5 * x = 0
Combine like terms:
10 * x - 30,000 = 0
Isolate x:
10 * x = 30,000; x = 3,000.
Therefore, the manufacturer must sell at least 3,000 items per month in order to "break even."

To solve this problem we must first find out how cups he must sell without tax to break even. If each cup of lemonade costs a quarter and he has spent \$20 on supplies, that means in order to make back the original \$20 he spent, he must sell 
. Due to this 4% business tax, he must sell 4% more in order to break even. To find that amount, we simply multiply that 4% by the number of cups he must sell without tax to break even, 
. He must sell an additional 3.2 cups in order to break even, however it is impossible to sell 0.2 of a cup of lemonade, therefore he must sell a minimum of 84 cups of lemonade in order to break even.
