tony misplaced 7 stamps from his collection. He knows that each stamp of his worth $0.15 and that the total value of them is now only $5.55. write an equation to determine the number of stamps (s) that tony originally had.
First we divide the total value of the stamps he has left with the cost so its: $5.55÷$0.15 = 37 so now he has 37 stamps just add the number of his misplaced stamps 37 + 7 = 44 Tony originally had 44 stamps
