A flower shop had 242 roses. On Saturday it sold 128 of the roses. On Monday the shop got some more roses to sell. Now it has 150 roses. Which set of equations can be used to find r, the number of roses the shop got on Monday?

• 242 – 128 = 114 150 + 114 = r

• 242 – 150 = 92 128 – 92 = r

• 242 – 128 = 114 150 – 114 = r

• 242 + 128 = 370 370 – 150 = r

Each Saturday Mr. Franklin teaches 3 piano lessons at his music school and 4 piano lessons in students’ homes. - For each lesson at his music school, he charges $15. - For each lesson in a student’s home, he charges $20. Which set of equations can be used to find m, the amount of money in dollars Mr. Franklin earns from piano lessons each Saturday?

• 15 x 4 = 60,

  20 x 3 = 60,

  60 + 60 = m

• 15 ÷ 3 = 5,

  20 ÷ 4 = 5,

  5 + 5 = m

• 15 x 3 = 45,

  20 x 4 = 80,

  80 - 45 = m

• 15 x 3 = 45,

  20 x 4 = 80,

  45 + 80 = m
