Of is the clue for multiplication Are becomes the equal sign.
15 × 6 = ? how many altogether?
90 = the number of seats.
Answer:
Sample Response: First, the variable needs to be determined. Then identify key words and translate the description. If possible, create a model, such as a diagram or table. Then write the equation using the variable.
