Davida worked 35 hours on each of Weeks 1 and 2. She worked 48 hours each of Weeks 3 and 4. How many more hours did Davida work on Weeks 3 and 4 than on Weeks 1 and 2?
Week 1 + Week 2 = 35 + 35 = <<35+35=70>>70 hours
Week 3 + Week 4 = 48 + 48 = <<48+48=96>>96 hours
Subtract Weeks 3-4 from Weeks 1-2 = 96 - 70 = <<96-70=26>>26
