To determine the Earnings of Shelley last week, we need to make relations with the values that are given. We let x as the total amount she earned last week by x and y as the additional amount she earned this week We do as follows:
20% additional amount she earned this week = y / 72 - y
y = $ 12
x = 72 - 12 = $60 total earnings last week
First let's put in the values.
-8(-2-3·-4)
Solve using PEMDAS
Parentheses (Multiplication)
-8(-2+12)
Parentheses (Addition)
-8 · 10
Multiplication
-80
The answer is -80
1/4 = 3/12, and 5/4 = 15/12, so it looks like there's a common difference between terms of 4/12 = 1/3. The the 
-th term in the sequence is given recursively by
By substitution, we get
and doing this again and again until we stop with an expression containing 
, we find that
Then the 12th term in the sequence is
EE is a representation of "x10^)

has the solution, well, , so that's not the answer.
is always true, so that's not the answer.
is always not true, so that must be the answer.
So, the answer is C)
