Margo is putting carpet in her 12 x 13 foot bedroom. She wants to buy an additional 15 square feet of carpet. Which equation can be used to find c, the total amount of carpet Margo will purchase?

• C = 12 x 13 + 15

• C = 12 x 13 - 15

• C = 12 x 15 + 13

• C = 12 x (13 + 15)

Jimmy had 210 marbles. He gave 35 marbles to his brother and put the remaining marbles into 5 bags. Which equation can be used to find m, the number of marbles in each bag?

• m= (210+35) ÷ 5

• m= (210+35) - 5

• m= (210 - 35) ÷ 5

• m= (210- 35) x 5

Finley scored 24 two point shots and 3 three point shots at her basketball game. Which equation can be used to find p, the number of points Finley scored at her game?

• p = (24 x 3) + (2 x 3)

• p= (24 x 2) + (3 x 3)

• p = 24 x 3 x 2 x 3

• p = (24 x 3) - 2 x 3

Norah had 125 pennies. She used 35 pennies to buy a tootsie roll at the gas station and gave half of what was left to her sister. Which equation can be used to find p, the number of pennies Norah has now?

• p= 125+ 35 x 2

• p= (125+35) ÷ 2

• p= (125-35) ÷ 2

• p= (125-35) x 2

Sara is following the Zone diet and needs to consume 120 grams of protein each day. Which equation can be used to find p, number of protein bars Sara will need to eat each day if it is her only source of protein and each protein bar contains 23 grams of protein?

• 120 - 23 = p

• 120 = 23 x p

• 120 x 23 = p

• 120 = 23 $\div$ p
