Define a variable and then write and solve an equation to solve the problem. Remember to write your answer as a complete sentence.

Use this information to construct the 5-D process.

**3 column labels: Define, do, and decide. Under define, there are 3 columns, labeled as follows: Painting #1, 5, x; Painting #2, x; Painting #3, $1500. Under do, the column is labeled, Solve for unknown painting prices, by totaling the parts: 5 x, +, x, + 1500 = Total Price. Under Decide, the column is labeled $13,500.**

Use these guidelines to run your own trials in order to find the values of that will total

Then, see if Painting #1 or Painting #2 is the most expensive painting.

A trial run example is done for you.

**Another row is added to the table, from left to right, as follows: 5 times $1000 = $5000, $1000, $1500, $5000, + $1000, + $1500 = $7500. Too low.**
