Let x be the cost of the gum 20 years ago. The gum costs 75 cents today. Twenty years ago, today's cost of 75 would be 3 cents less than three times the cost x.

@Tracy96 Want to do the next step?

OpenStudy (anonymous):

Hmm.. lemme take a look!

Directrix (directrix):

Okay. Take your time.

@___.randa.___ Stay in the thread, okay?

OpenStudy (anonymous):

I'm not good with the explanation, I just jump on to the answer XD lol So if it's 3 cents (0.3) less that 3*x then it should be option B?

OpenStudy (anonymous):

than*

Directrix (directrix):

Is that .3 in the B option .3 of a dollar which is 30 cents?

OpenStudy (anonymous):

oh my bad, that's incorrect! Then it's gotta be C

Directrix (directrix):

Option C is what I got. The question mentions 3 cents and 75 cents with no decimal points so the answer does not require any decimal points. Plus, I don't see any decimal responses that are correct.

OpenStudy (anonymous):

True, if it were to be in decimals it had to be 0.03 and 0.75

Directrix (directrix):

The gum cost 26 cents 20 years ago if that is of interest. :)

OpenStudy (anonymous):

Haha *thumbs up*
