The cricket make approximately 3 chirps in 15 seconds if the temperature is 80°F.
Step-by-step explanation:
We are given the following in the question:
The above equation is used approximate the temperature y in degrees Fahrenheit based on the number of chirps x a cricket makes in 15 seconds.
The attached image shows the graph for the given equation.
Now, we have to find the number of chirps a cricket will make in 15 seconds if the temperature is 80°F.
Putting y = 80 in the given equation, we get:
Thus, the cricket make approximately 3 chirps in 15 seconds if the temperature is 80°F.

Inequality: 0.08x + 2300 ≥ 2800
Liz needs to sell products of $6250 at least.
Step-by-step explanation:
Given that:
Per month salary of Liz = $2300
Commission = 8% = = 0.08
Amount Liz wants to earn = $2800
Let,
x be the amount of sales.
0.08x + 2300 ≥ 2800
0.08x ≥ 2800 - 2300
0.08x ≥ 500
Dividing both sides by 0.08
Hence,
Liz needs to sell products of $6250 at least.
