Given:
54 gal of hot water tank holds 450 lb of water.
Let's find the amount of water a 69 gal tank will hold.
Here, we have:
54 gal = 450 lb
69 gal = x lb
Now, apply the proportionality equation:
[tex]\frac{450}{54}=\frac{x}{69}[/tex]Cross multiply:
[tex]\begin{gathered} 54x=450*69 \\ \\ 54x=31050 \end{gathered}[/tex]Divide both sides by 54:
[tex]\begin{gathered} \frac{54x}{54}=\frac{31050}{54} \\ \\ x=575 \end{gathered}[/tex]Therefore, a 69 gal tank will hold 575 lb of water.
ANSWER:
575 lb of water
