Given:
Entrance fee = $5.50
Additional fee = $1.25 for each activity.
Total amount spend at fair = $30
To find:
The equation that represents the problem.
Solution:
Let the number of activities be
.
Additional fee for 1 activity =
![\$1.25](https://img.qammunity.org/2022/formulas/mathematics/high-school/lbm1aae7tivcq0rs7kxrmg3rwyub2px96n.png)
Additional fee for x activity =
![\$1.25x](https://img.qammunity.org/2022/formulas/mathematics/high-school/com2g17p9pddv13jmbltsxnmtecgaus14m.png)
Total fee = Entrance fee + Additional fee for x activity
=
![\$5.50 + \$1.25x](https://img.qammunity.org/2022/formulas/mathematics/high-school/4qyw15fotgm7aaq219sidq8aln9a9ac0st.png)
It is given that Kevin has at most $30 to spend at the fair. So, total fee must be equal to $30.
![\$5.50 + \$1.25x=\$30](https://img.qammunity.org/2022/formulas/mathematics/high-school/1lxgra8mo4s7ufjfs7q7bzejt69rfshwgd.png)
![5.50+1.25x=30](https://img.qammunity.org/2022/formulas/mathematics/high-school/801v1ozlnymuob6a3rynmy02o7n7unp2p2.png)
Therefore, the require equation is
.
