Kate is saving to take an SAT prep

course that costs $350. So far, she has

saved $180, and she adds $17 to her

savings each week. Which equation represents this situation?

• 350 + 17w = 180

• 17 + 180w = 350

• 17w + 180 = 350

• 17w - 180 = 350

At Joe's Clown Car Rental Agency, renting a car costs $35 plus $0.75 for every mile it is driven.  What is an equation that can be used to find the number of miles, m, a vehicle was driven, if the total rental charge was $222.50?

• 222.5 = m(35 + 0.75)
• 222.5 = 35 + 0.75m
• 222.5 = 0.75 + 35m
• 222.5 = 0.75(m + 35)
