Question

a seventh grade class is having a raffle to raise money for a field trip. they have already raised $100, and will raise $6 for every ticket they sell. how many tickets do they need to sell to raise exactly $154?
youre trying to write an expression to represent the total amount of money the class has raised. you know that they get $6 for every ticket they sell, t. first write an expression to represent the amount of money the class earns for every ticket they sell.
you can multiply the number of dollars per ticket, 6, by t, the number of tickets. how can you show 6 multiplied by t?

Explanation:

Step1: Define expression for ticket earnings

Let $t$ = number of tickets sold. Earnings from tickets: $6t$

Step2: Set up total money equation

Total raised = existing + ticket earnings: $100 + 6t = 154$

Step3: Solve for $t$

Subtract 100 from both sides: $6t = 154 - 100 = 54$

Step4: Calculate $t$

Divide by 6: $t = \frac{54}{6} = 9$

Answer:

1. Expression: $6t$
2. Number of tickets: 9
