1) Write a real world problem that can be modeled by the equation: 1.25x = 0.75x + 50
2) Write an equation with the solution x=20. The equation should have the variable on both sides, a fractional coefficient on the left side, and a fraction anywhere on the right side.
3) Write an equation with the solution x=25. The equation should have the variable on both sides, a decimal coefficient on the left side, and a decimal anywhere on the right side. One of the decimals should be written in tenths, the other in hundredths.
