Maddy solves the equation -2.5 ( x - 4 ) = -3x + 4 for x. Some of his steps are shown
Step 1: -2.5x + 10 = -3x + 4
Step 2: -2.5x + 10 = -3x + 4
Step 3: .5x + 10 = 4
Step 4: .5x = -14

Sadie, Logan and Ava each wrote expressions to represent their hourly earnings for an after-school job where h represents the number of hours worked.
Sadie: 4(2h + 4)
Logan: 7.25h + 20
Ava: 8h + 24
How many hours will Sadie and Ava have to work in order to make the same amount of money in one week? Write and solve an equation.
4(2h + 4) = 8h + 24; Always
7.25h + 20 = 8h +24; 1 hour
4(2h + 4) = 8h + 24; Never
8h + 24 = 4(2h + 4); 8 Hours
