Alright, lets get started.
Suppose the cost of the gum 15 years ago is = x
Today's cost is 4 cents less than four times what the pack cost 15 years ago.
Means
todays cost =
......................equation
Adding 4 in both sides
Dividing 4 in both sides
x = 13.5
Hence price of gum 15 years ago was 13.5 cents. : Answer
Hope it will help :)
