-2 is the correct answer.
The sale price S (in dollars) of an item is given by the formula
S=L−rL , where L is the list price (in dollars) and r is the discount rate.
Since, S = L -rL
rL = L -S
r = 
r = 
Since, the listed price of the shirt is $30, we have to find the discount rate.
Therefore, r =
is the discount rate.
Basically think of linear functions/equations as something with a constant value or consistent result. For example: (Attachment)
Equation= x divided by -9 = -16
solve= 9 x 16 = 144
answer is 144
