Exploring Standard Form Word Problems

What is the general form of a standard form equation?

• ax - by = 0

• ax - by = c

• ax + by = 0

• ax + by = c

In a standard form equation, what do 'a' and 'b' typically represent?

• Constants

• Total values

• Unknown variables

• Rates or coefficients

In the example problem, what does the 'c' value represent?

• The total cost

• The cost of hamburgers

• The cost of hot dogs

• The number of items

If Sam ordered 2 hamburgers and 3 hot dogs, and the total bill was $19.50, what is the equation setup?

• 2x - 3y = 195

• 2x - 3y = 19.50

• 2x + 3y = 195

• 2x + 3y = 19.50
