An exponential model will be the best for the data.
Step-by-step explanation:
If you chart this data (either using a calculator, excel, or an online tool like desmos), it is clear that the curve is exponential.
Furthermore, if you run regression, you can find that the curve [tex]4*2^x[/tex] fits the data quite nicely.

Answer:
See below
Step-by-step explanation:
1/3 (300000) = 100 000 80% of this = 80 000
2/5 (300000) = 120000 125% of this = 150 000 total so far = 230 000
Overall 10% profit would yield 300000(1.1) = 330 000
the remaining land needs to sell for
330 000 - 230000 = 100 000

Renee is buying Halloween candy. She wants to buy candy bars and lollipops and spend no more than $28. Each candy bar costs $0.45 and each lollipop costs $0.25. Which inequality represents the possible combinations of x, the number of candy bars, and y, the number of lollipops Renee can buy?
Answers
The inequality that represents the possible combinations of candy bars and lollipops that he can buy is given by:
[tex]0.45x + 0.25y \leq 28[/tex]
What is the inequality that models this situation?The total price can be no more than $28, hence:
[tex]T \leq 28[/tex]
Each candy bar costs $0.45 and each lollipop costs $0.25. x is the number of candy bars and y of lollipops. Hence, the total price is given by:
T = 0.45x + 0.25y.
Hence, the inequality that models the situation is:
