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?
es )

75=3(x)-3

Step-by-step explanation:

Translating the words into math, we get the following:

"A pack of gum costs 75 cents." tells us that a pack of gum is 75 cents.

"That is 3 cents less than three times what the pack cost 20 years ago" tells us that 3(x)-3 cents is how much it costed 20 years ago.

Setting these equal we get 75=3(x)-3 which tells us that x=26 which means the pack of gum costed 26 cents 20 years ago.

it could be 1,3 and more others to create a cylinder.
