A.) 3.2 pounds package has a shipping cost of $4.13. We can't use the cost assigned to 3 lbs because the package is over 3 lbs but it is not over 4 lbs so we use the cost of 4lbs.

b) It is better to use a line graph where x values represent the weight in pounds and the y values represent the cost.

c) f(x) = 2.69 + 0.48(x-1)

d) domain is the x values; range is the y values

Leona [35]

If the paint is 30% yellow, and you used 72 ounces of yellow, all you have to do is divide 72 by 30% to get the whole amount of ounces of paint made.
72 ÷ 0.30 = 240
In the last batch, you made 240 ounces of melon madness paint.

Answer:

You would have approximately 201 insects.

Step-by-step explanation:

To calculate the final population of the insects, you need to first insert the values of each variable you know into the equation. The initial population at time $t=0$ would be 100 insects, the rate of population growth coverted to decimal form would be 0.1, and the elapsed time since time $t=0$ is 7 days. Now the new equation would be $P = 100(e)^{0.1*7}$ .

$P = 100(e)^{0.1*7}$

⇒ $P$ ≈ $100 * 2.01$

⇒ $P$ ≈ $201$

You will have 201 insects in 7 days (rounded to the nearest insect).
