1. Megan purchased a new gadget for her technology hobby. She plans to sell it sometime in the future; however, its value depreciates monthly. The expression shows the depreciated sales value of the gadget: 2,020 − 22m
What does the second term of the expression represent?

The number of months Megan will wait to sell the gadget
The original value of the gadget
The monthly depreciation value of the gadget
The total depreciation value of the gadget

2. An inequality is shown:

−np − 5 ≤ 4(c − 2)

Which of the following solves for n?

n ≥ the quantity 4 times c minus 3 all over negative p
n ≥ the quantity 4 times c minus 13 all over negative p
n ≤ the quantity 4 times c minus 3 all over negative p
n ≤ the quantity 4 times c minus 13 all over negative p

3. Solve the rational equation x over 4 equals x squared over quantity 3x plus 3 and check for extraneous solutions.

x = −3; x = 0 is an extraneous solution
x = 0; x = −3 is an extraneous solution
x = 0 and x = 3
x = 0 and x = −3
