Rylie cooks pizzas at a restaurant. She cooks 5 pizzas on Wednesday, 9 pizzas on Thursday, and 4 times as many pizzas on Friday as on Thursday.

Complete the equation to show P, the total number of pizzas Ricardo cooks on Wednesday, Thursday, and Friday.

________ + _________ + (________ x ________) = P

• 5 + 9 + (4 x 9) = P

• 5 + 9 - (4 x 9) = P

• 5 x 9 + (4 x 9) = P

• 5 x 4 + (9 x 9) = P

Porter counts 14 robins and 18 sparrows in his neighborhood. Kasen counts 4 times as many birds as Porter at the wildlife center.

Let T be the total number of birds Porter counts and B be the total number of birds both Porter and Kasen count. Which pair of equations could be used to find the total number of birds Porter and Kasen count?

• T = 4 x (14 + 18)

  B = 4 x T

• T = 14 + 18

  B = 4 x T

• T = 14 + 18

  B = T + (14 x 4)

• T = 14 + 18

  B = T + (4 x T)

Allie and Molly bought 4 pizzas that cost $7 each and breadsticks that cost $3. They split the cost between them. Which equations could be used to find how much each paid? Let T stand for the total cost and E stand for the amount each paid.

• T = (4 x 7) + 3

  E = T x 2

• T = (4 x 7) + 3
  E = T $\div$ 2

• T = (7 + 3) x 4
  E = T $\div$ 2

• T = (4 + 7) x 3
  E = T $\div$ 2

The McDowell family recycled 37 cans one week and 24 cans the next week. The Grigsby family recycled twice as many cans as the McDowell family.

Which equations could be used to find the total number of cans both families recycled? Let M stand for the McDowell family and B stand for both families. Circle the letter of the correct answer.

• M = 2 x (37 + 24)

  B = 2 x M

• M = 37 + 24

  B = 2 x M

• M = 37 + 24

  B = M + (37 x 2)

• M = 37 + 24

  B = M + (2 x M)

A bike rental is $20 for a day and $3 for an hour. Gentry rented a bike for 2 days and 2 hours. Which equation could you use to find how much money, M, Gentry spent? Choose all that apply.

• M = (2 x 20) + (2 x 3)

• M = (3 x 20) + (2 x 2)

• M = (20 x 2) x (3 x 2)

• M = (20 x 2) + (3 x 2)

Kendall earns $15 an hour at her tutoring job and $10 an hour babysitting. Last week, she worked 10 hours tutoring and 4 hours babysitting. Which equation shows how much Kendall earned, E?

• E = (15 x 10) + (10 x 4)

• E = (15 + 10) x (10 + 4)

• E = (15 x 10) x (10 x 4)

• E = (15 x 4) + (10 x 10)
