Hey there!
If the price of a CD on sale is 0.65c, then 0.35 was taken off of the original price. You can find this if you subtract 0.65 from 1, or 65% from 100%.
Your answer would not be your second option or your fourth option, since the price you're paying is 0.65 of the original price and you are getting 0.35 of the price off. Also, your third option wouldn't be correct either, since 0.35 isn't being added on top of the total price.
Your answer is your first option.
Hope this helped you out! :-)

square both sides:
add 4 in both sides:
divide both sides by 4:
substitute back:
and we're done!
