Ans: $\$520$
Let $\$x$ be the cost of the vase.
Let $\$x$ be the cost of the vase.
Then the marked price
$\begin{array}{cl}
= & x (1 + 30\%) \\
= & \$1.3x
\end{array}$
With discount $40\%$ on the marked price, $\$88$ will be loss. Hence, we have
$\begin{array}{rcl}
x – 88 & = & 1.3x \times (1- 40\%) \\
x – 88 & = & 0.78x \\
0.22 x & = & 88 \\
x & = & 400
\end{array}$
Therefore, the cost is $\$400$.
Hence, the marked price of the vase
$\begin{array}{cl}
= & 400 \times 1.3 \\
= & \$520
\end{array}$
