Horatio went to a stamp collection show. While at the show, he purchased an empty stamp book for $18 and some collectible stamps for $1.25 each. He spent a total of $26.75. Let s represent the number of collectible stamps Horatio purchased. Enter an equation that can be used to find the number of stamps that Horatio purchased

18 + 1.25s = 26.75

Step-by-step explanation:

Given :

Cost of empty stamp = $18

Cost per collectible stamp = $1.25

Total amount spent = $26.75

Number of collectible stamps = s

Equation to represent the number of stamps purchased :

Total amount spent = (number of empty stamp*cost of empty stamp) + (number of collectible stamps * cost per collectible stamp)

26.75 = (1 * 18) + (1.25 * s)

18 + 1.25s = 26.75

1.25s = 26.75 - 18

1.25s = 8.75

s = 7
