Answer:
$19.99 for each cartridge.
Step-by-step explanation:
For this problem, we are finding the cost of the three printer cartridges. Since the problem says that the tax was 5.95, we can subtract that from 90.91.
90.91-5.95=
84.96
Next, since we know that the software package was 24.99, we can subtract that from 84.96.
84.96-24.99=
59.97
Finally, since there are three printer cartridges, we can divide 59.97 by 3, and get our answer.
59.97/3=
19.99
Each printer cartridge would cost $19.99.
Hope this helps and have a good day! :D
Multiply both sides by 10.
2b=990
divide both sides by 2
b= 495
Less, 78.01 has a one in the hundredths place, while 78.006 has a 0, and 0 < 1.

Answer:
31 human cases.
Step-by-step explanation:
The least squares line equation for the number of reported dead birds (x), versus the number of human West Nile virus cases (y) is
y = -10.2638 + 0.0491x
If the number dead birds reported in a year is 844, then we have to find the numbers of human cases of West Nile virus.
To find the numbers we will plug in the value of x = 844 in the linear equation.
y = -10.2638 + 0.0491(844)
= -10.2638 + 41.4404
= 31.1766
≈ 31
Therefore, 31 human cases can be expected.
