Here's a revised version with corrected grammar and unnecessary words removed: The student council is planning an activity night to raise money. There will be a charge of $5 per student to attend. Part A: Write an expression that can be used to calculate the number of students. Part B: The cost to rent the venue is $200, and the council aims to raise $350 after paying for the rental. How many students need to attend the activity night for the student council to cover the rental cost and reach their goal?

Part A: To calculate the number of students who attend the activity night, you can use the following expression:

Let x represent the number of students attending.

The expression will then be: 5x

This expression indicates that each student will pay $5, so the total amount of money raised will be 5 times the number of students.

Part B: To determine how many students need to attend the activity night for the student council to cover the rental cost and reach their fundraising goal, you need to set up an equation.

The total money raised should be equal to the rental cost ($200) plus the additional amount they aim to raise ($350). So, the equation will be:

5x = 200 + 350

Combine the amounts on the right side of the equation:

5x = 550

To find the number of students x, divide both sides by 5:

x = 550 / 5

x = 110

So, the student council needs 110 students to attend the activity night to cover the rental cost and meet their fundraising goal.
