Lauren has 188 songs on her iPod. This is five less than twice as many songs that Brad has. How many songs does Brad have on his iPod? Which expression represents this problem?

• 188 + 5 + 2s

• 188 - 2s = 5

• 5 - 2s = 188

• 2s - 5 = 188

• 188 + 5 = 2s

A car rental company charges $56 per day plus $0.30 per mile driven. John paid $86 after renting a car for one day. What equation should he use to find x, the number of miles he drove?

• x + 56 = 86

• 30x + 56 = 86

• 0.30x + 56 = 86

• 0.30x + 86 = 56

• 56x + 30 = 86
