<h3>What is a profit?</h3>
The profit is given by the <u>subtraction of the revenue by the total costs</u>.
In this problem:
- For the dozen cookies, she earned a revenue of 6 dollars.
- In all, the total cost of the 12 cookies was of 0.5 + 0.7 + 0.4 + 0.4 = 2 dollars.
6 - 2 = 4, hence she makes a profit of $4.

First take note of her total amount of money, the amount of magazine cost, and the total weeks they purchased it.
Total: $88
Cost: $3.75
Weeks: 5
Now setup and equation.
88-(3.75 x 5)
88-18.75=69.25
So she will have $69.25 after the 5 weeks of purchasing magazines
Step-by-step explanation:
By Geometric mean property:
The diagonal is solved by a^2+b^2=c^2
c=8 in this problem, so c^2=64
Since the figure is a square, a must equal b.
64/2=32, each side is root of 32 units
the square root of 32 is approximately 5.66.
