Painting Price and Equation Problems

Mr. Dell guides students through solving a word problem involving the sale of gorilla paintings. The problem requires defining variables, formulating an equation, and solving for unknown values. The solution involves determining the price of each painting, with the first painting being the most expensive. The video emphasizes the importance of understanding the problem, defining variables, and solving equations step-by-step.

What is the primary goal when writing an equation from a word problem?

• To find the total cost

• To solve for unknown values

• To list all known values

• To rewrite the problem in simpler terms

Which painting's price is defined as the variable x?

• First painting

• All paintings

• Third painting

• Second painting

What is the expression for the price of the first painting?

• 3x

• 5x

• 2x

• x

What is the equation formed to solve the problem?

• x + 5x + 1500 = 13500

• x + 4x + 1500 = 13500
