Answer:
After how many years is the fish population 100?
x=3.97 years
Step-by-step explanation:
The fish population increases by a factor of 1.5 each year. We have the equation that represents this situation

Where x represents the number of years elapsed f(x) represents the amount of fish.
Given this situation, the following question could be posed
After how many years is the fish population 100?
So we do
and solve for the variable x

Observe the solution in the attached graph
Answer:
Breyana paid 88% of the dress's original price.
Step-by-step explanation:
We are given the following in the question:
Let x be the original price of dress.
The dress is on sale for 20%.
Price of dress after discount =

Breyana will also have to pay 10% sales tax on the discounted price of the dress.
Price of dress after discount =

Total cost of dress =

We have to calculate percentage of original price paid by Breyana

Thus, Breyana paid 88% of the dress's original price.
Looking at the graph, you can see that as more weeks pass, the amount of tickets sold are slowly decreasing.
Therefore, A) As the number of weeks increases, the number of tickets sold decreases would be the correct answer.
Answer: The cost will be same for 6 hours.
Step-by-step explanation:
Given: A jet ski company charges a flat fee of $22.00 plus $3.00 per hour to rent a jet ski.
Another company charges a fee of $17.50 plus $3.75 per hour to rent the same jet ski.
Let x = Number of hours
y = Total cost
Then, Total cost (in $) for first company (y) = 22+3x
Total cost (in $) for second company (y) = 17.50+3.75x
So required system of equations :
y = 22+3x
y= 17.50+3.75x
When the cost will be the same,
22+3x = 17.50+3.75x
⇒ 3x - 3.75x = 17.50- 22
⇒ - 0.75x = -4.5
⇒ x =6 [Divide both sides by -0.75]
Hence, the cost will be same for 6 hours.
