*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 lesson each Saturday?

• 15 $\times$ 4 = 60
  20 $\times$ 3 = 60
  60 $+$ 60 = m

• 15 $\div$ 3 = 45
  20 $\div\$ 4 = 5
  5 + 5 = m

• 15 $\times$ 3 = 45
  20 $\times$ 4 = 80
  80 $-$ 45 = m

• 15 $\times$ 3 = 45
  20 $\times$ 4 = 80
  80 $+$ 45 = m
