Question

A pack of gum costs 75 cents. That is 3 cents less than three times what the pack cost 20 years ago. Which equation could be used to find the cost of the gum 20 years ago?

Answer 1

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.

Answer 2

C) 3x - 0.03 = 0.75
