| 1) Tamilselvi bought a box of pushpins. She put 47 pushpins on the bulletin board and had 64 left. Which equation, when solved, will tell how many pushpins were in the box
Answer: 4 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve:
You can use the variable F to represent the number of pushpins in the box.
F = number of pushpins in the box
(number of pushpins in the box) – (number of pushpins on the bulletin board) = number of pushpins left F – 47 = 64

| 10) Chidambaram collected 69 seashells on the beach. Then, some of the shells got caught in a wave and washed back out to sea. He has 22 seashells left. Which equation, when solved, will show how many seashells washed out to sea
Answer: 4 SOLUTION 1 : Remember: A variable is a letter that represents an unknown number. Solve:
You can use the variable S to represent the number of seashells washed out to sea.
69 = total number of seashells
(total number of seashells) – (number of seashells washed out to sea) = number of seashells left 69 – S = 22
