Pressure in Tank with Two Liquids

APPH12-FEIOSF

What is the pressure $50.0$ $cm$ from the bottom of a $5.00$ $m^3$ tank if it is filled with $3.50$ $m^3$ of a liquid with a specific gravity of $1.23$ and $1.00$ $m^3$ of a second liquid with a specific gravity of $ 0.900$? The bottom of the tank has a surface area of $1.00$ $m^2$. Use $1.01\times10^5\ Pa$ for atmospheric pressure and $9.8\ m/s^2$ for $g$. Assume the liquids have settled into two separate layers. The diagram below is not drawn to scale.
