A rental company at Best Bargain Rental costs $150 a week, plus $0.10 per mile.  Which equation represents the relationship between the number of miles (x) and the total cost in dollars (y) for a 2- week period?

• y = 2(150)(0.10x)
• y = 2(150) + 0.10x
• y = 150 + 2(0.10x)
• y = 2(150 + 0.10x)

Two 8th grade classes are selling raffle tickets to raise money.  
One class is selling tickets for $2.50 each and has already raised $350.
The other class is selling tickets for $3.00 each and has already raised $225.
Which equation can be used to find t, the number of tickets each class needs to sell so that the total amount raised is the same for both classes?

• 3t + 350 = 2.50t + 225
• 350t + 2.50 = 225t + 3
• 2.50t + 350 = 3t + 225
