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
![y=32.5+x](https://img.qammunity.org/2023/formulas/mathematics/college/jb2w7xcvl01n2abzeoycc95yfm83ipixoz.png)
Where y is Jessica and x is Jerry.
Now, we can find Jessica's climb.
![y=32.5+25=57.5](https://img.qammunity.org/2023/formulas/mathematics/college/mput6o4fettb0lalv81j76urogdh88chgx.png)
Hence, Jessica climbed up 57.5 feet.
The expression is
![y=32.5+25](https://img.qammunity.org/2023/formulas/mathematics/college/6j05py65mysvfc1aufokzosak16c6u1xaf.png)
