We know that
• Jerry climbed 25 feet up the mountain.
,• Jessica climbed 32 and a half feet up the mountain higher than Jerry.
Based on the given information, we can write the following expression
[tex]y=32.5+x[/tex]Where y is Jessica and x is Jerry.
Now, we can find Jessica's climb.
[tex]y=32.5+25=57.5[/tex]Hence, Jessica climbed up 57.5 feet.
