Question

Tony misplaced 777 stamps from his collection. He knows that each stamp of his is worth \$0.15$0.15dollar sign, 0, point, 15 and that the total value of them is now only \$5.55$5.55dollar sign, 5, point, 55.

Answer 1

Write an equation to represent the value of his stamp collection in terms of the number of stamps, s, that he had originally, and find the value of s.

Tony misplaced 7 stamps

Each stamp worth = $0.15

Total value of stamp now = $5.55

Let the number of stamps be 's'

Number of stamps now = s - 7 (misplaced 7 stamps)

price (number of stamps now ) = 0.55

0.15 (s - 7) = 5.55

Divide by 0.15 on both sides

s - 7 = 37

Add 7 on both sides

s = 44

Total number of stamps originally he had = 44 stamps

Answer 2

There is no question being asked. If the answer needed is how many stamps does he have left take the total value and divide by the worth of each stamp. 5.55/0.15 = 37
