  7. Problem Solving Strategy Write an Equation

  8. In two days Lupe hiked 65 km. She hiked 34.3 km the first day. How far did she hike the second day? Let x = km that Lupe hiked the second day. 34.3 km x 65 km x = 65 - 34.3 65 = x + 34.3

  9. Dan earns $3 for every lawn he mows. How many lawns must he mow to earn $54? Let x = # of lawns mowed $54 = x • $3

  10. Michele = 16 Tania sold three times as many tickets as Michele. Michele sold 16 tickets. How many did Tania sell? Let T = tickets that Tania sold T = 3 • 16
