Bode and Grace solve the equation 1.2 = 6(4 - 0.4g) - 4.8 for g in different ways. Bode begins solving by dividing both sides of the equation by 6 and then adding 4.8 to both sides.
Grace begins solving by adding 4.8 to both sides of the equation and then dividing both sides by 6.
Whose strategy is best? Why?
Grace's strategy is best because adding 4.8 to both sides of the equation means that the left side will simplify to the whole number 5.
Bode's strategy is best because adding 4.8 after dividing by 6 will eliminate a term on the right side of the equation.
Bode's strategy is best because first dividing by 6 then adding 4.8 will solve the equation in the fewest number of steps.
Grace's strategy is best because first adding 4.8 then dividing by 6 will solve the equation in the fewest number of steps.
