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?

Tap to reveal answer
12% of 15,000 is 0.12 * 15,000 = 1800.
8% of 15,000 is 0.08 * 15,000 = 1200; therefore in total, Mary spent 1800 + 1200 = $3000 more.
12% of 15,000 is 0.12 * 15,000 = 1800.
8% of 15,000 is 0.08 * 15,000 = 1200; therefore in total, Mary spent 1800 + 1200 = $3000 more.

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?
Tap to reveal answer
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%.

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."

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

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.

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.
