Using the profit concept, it is found that she makes a profit of $4 selling a dozen cookies for six dollars.
<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.

Use formula: an = a1 * r^(n-1)
a1 = 2, r = -2
a12 = 2 * -2^(12-1)
a12 = 2 * -2^11
a12 = 2 * -2048
a12 = -4096
Solution: -4096
Answer:
x = 32/3
Step-by-step explanation:
p(x) = 13
x + 7/3 = 13
x = 13 - 7/3
x = 32/3
0.5=0.85^x taking the natural log of both sides...
ln0.5=x ln0.85
x=ln0.5/(ln0.85)
x≈4.265
Then:
f=20000(0.85)^(4.265)
f=$10000.00 to nearest dollar
