What is the formula for calculating the return on assets?
Two methods
1. Total profit / total assets = asset profit margin
2. Net profit / total assets = net profit margin of assets (after income tax)
Ask the profit rate calculation formula
If the purchase price of a bottle of Wahaha nutrition express is 3 yuan and the retail price is 4 yuan,
If the purchase price of a package of spicy food is 1.2 yuan and the retail price is 2.5 yuan, the profit will reach 50%, right?
Or how to calculate?
1. The calculation formula of profit margin is as follows:
Sales profit rate = profit / sales revenue
=(sales revenue cost of sales) / sales revenue
2. According to the above formula:
Profit margin of a bottle of Wahaha nutrition express = (4-3) / 4 = 25%
That is to say, if you sell 100 yuan, you can get a profit of 25 yuan
There is a purchase price and a profit margin of 30%. To find the selling price, we need a formula
Let the purchase price be a and the selling price be B
Profit margin = price difference between purchase and sale / selling price
0.3＝（B-A）/B 0.3B＝B-A 0.7B＝A B＝A/0.7
Selling price = purchase price / 0.7
The selling price is 91. The profit margin is 40%. How much is the purchase price? The calculation formula,
91 divided by 1 + 40% = 65
-1+2-3+4-5+… +2012-2013=______ ．
-1+2-3+4-5+… +2012-2013=（-1+2）+（-3+4）+（-5+6）+… +(- 2011 + 2012) - 2013 = 1006-2013 = - 1007
In the triangle ABC, ad is perpendicular to BC, ad equals BC equals a, AC equals B, AB equals C, find the maximum value of B / C + C / b

What about the picture
The area of a parallelogram is 24 square centimeters larger than that of a triangle with the same height and bottom. What is the area of this triangle______ Square centimeter
The area of parallelogram is: 24 × 2 = 48 (square centimeter) the area of triangle is: 48-24 = 24 (square centimeter) a: the area of this triangle is 24 square centimeter
Solve the following equation lgx + lgx ^ 2 + lgx ^ 3 + +lgx^n=n(n+1)
lgx+lgx^2+lgx^3+…… +lgx^n
=lgx+2lgx +3lgx + ...+ nlgx
=(1+2+...n)lgx
=n(n+1)/2 * lgx
So the equation is equivalent to n (n + 1) / 2 * lgx = n (n + 1)
That is, 1 / 2 * lgx = 1
lgx= 2
x=10^2=100
