Since $55 would be 80% of the original (since it was 20% off) you would divide the $55 by 4 to get 1/5 if the original price ($13.75) and multiply it by 5 to get the original price. $13.75x5=$68.75

$the \ original \ price : x \\ \\ x\cdot 20\% = 55 \\ \\x\cdot \frac{20}{100}=55\\ \\\frac{1}{5}x=55 \ \ / \cdot 5\\ \\x=\$ \ 275 \\ \\ Answer : \ the \ original \ price \ it \ \$ \ \ 275 .$

Write the explicit formula that represents the geometric sequence -2, 8, -32, 128

MissTica

So hmm the first term is -2

and if we divide one term by the term before it, we'd get the "common ratio" "r"

so hmm say -32/8 that gives us -4, so r = -4

thus $\bf n^{th}\textit{ term of a geometric sequence}\\\\
a_n=a_1r^{n-1}\qquad 
\begin{cases}
a_1=\textit{first term}\\
r=\textit{common ratio}\\
----------\\
a_1=-2\\
r=-4
\end{cases}\implies a_n=-2(-4)^{n-1}$
