So this is not a solution to our original equation.

Ask the student to determine the total amount of money Elijah would pay after one, two, three, and four months of membership. Assist the student in using these calculations to develop an equation that models the relationship among the quantities given in the problem.

So I'm going to move this up a little bit. Instructional Implications Explain to the student that writing and solving an equation is an effective strategy for solving mathematical problems. Plus three. In this problem, the objective in writing and solving the equation is to answer the question posed in the problem.

If you represent it with a variable, can you write an equation that models the relationship among the quantities described in the problem?

Color changing is hard. So this is the same thing as saying five times five minus three, let me do that in that same color, minus three, needs to be equal to four times five, four times five plus three, plus three. Have the student explain the meaning of the variable in context and the significance of the solution in solving the word problem.

Now, is this true? Can you explain how to determine the amount Elijah has paid so far?
