A home improvement store charges $4.00 per square foot for new carpet and an additional $2.00 per square foot for installation. Nydia wants to put a total of 900 square feet of new carpet in several rooms of her home. Which equation can be used to find C, the total cost of the carpet?

• C = 900 (4+2)

  C = 900 (6)

  C = $5,400

• C = 900 + 4 x 2

  C = 900 + 8

  C = $908

• C = 900 x 4 + 2

  C = 3,600 + 2

  C = $3,602

• C = (900 + 4) + (900 + 2)

  C = 904 + 902

  C = $1,806

Robin raises chickens and sells the eggs at the local farmer’s market. She sells the eggs for $4 per dozen. In the month of July, Robin sold 72 dozen eggs. She spent $76.89 for chicken feed and $23.45 for other supplies for the month. Which equation can be used to find P, Robin’s profit for the month of July?

• P = 72 x 4 - 76.89 + 23.45

• P = 72 x 4 - (76.89 + 23.45)

• P = 72 x 12 x 4 - (76.89 + 23.45)

• P = 288 - 12 (76.89 + 23.45)

On Friday, Mr. Singh filled his car with gasoline. He purchased 15 gallons of gasoline for $3.60 per gallon. On Saturday, Mr. Singh filled his wife’s car with gasoline. He purchased 13 gallons for $3.50 per gallon. Which equation can be used to find g, the total cost of the gasoline for both cars?

• g = (3.60 + 3.50) x (13 + 15)

• g = (3.60 x 13 ) + (3.50 x 15)

• g = (3.60 x 15 ) + (3.50 x 13)

• g = (3.60 + 15 ) + (3.50 + 13)
