Answer: My mom's height is 67.75 inches.
Step-by-step explanation: Given that my dad is 73.5 inches, I am 2.5 inches shorter than my dad. My mom is 3.25 inches shorter than me.
We are to find the height of the mom.
Since I am 2.5 inches shorter than my dad, so my height will be
[tex]h_m=73.5-2.5=71~\textup{inches}.[/tex]
Now, my mom is 3.25 inches shorter than me, so my mom's height is
[tex]h_{mom}=71-3.25=67.75~\textup{inches}.[/tex]
Thus, my mom is 67.75 inches tall.
