The answer to your question is: .75 = 3x - .03
How to solve it:
x = the cost of a pack of gum twenty years ago
.75 = 3x - .03
+ .03 + .03
.78 = 3x
/ 3 / 3
.26 = x
If a pack of gum now costs 75 cents, which is 3 cents less than three times what a pack would have cost 20 years ago, then a pack of gum would have cost 26 cents.
4/3 /......................................................../
$64.79 would be the cost after tax is added
