  1. Use a unit rectangle to represent this situation. Label the parts carefully.

    Draw a rectangle.

    Subdivide the rectangle and label appropriately.

    One dimension will represent the dealership's different types of cars, while the other will represent the dealership's different colors of cars.

    Shade half of them to represent the white cars, and three-fourths to represent the sedans. The area of the overlapping region is the answer.

  2. Write an equation or a sentence that describes the situation, and answer the question.

    Write an equation that finds the area of the overlapping region. Then you can find the answer.
    See problem 2-89 for examples.

  3. Write your answer from part (b) as a decimal and as a percent.

    Convert the fraction into a decimal by dividing the numerator by the denominator. Convert the decimal into a percent by multiplying it by or moving the decimal.
