come up with equation....

anonymous · Answer

let x be the original price

anonymous · Answer

price on monday would be .45x

anonymous · Answer

that would be the amount off

anonymous · Answer

im not understanding though, ive got x= .45x + .20x + 31.68???

anonymous · Answer

sorry about the wait... dog got outside.

anonymous · Answer

ok so where were we..
yeah so the equation is going to look like this:

anonymous · Answer

x-.45x-.2(x-.45x)=31.68

anonymous · Answer

-.45x is going to give you the amount of the discount

anonymous · Answer

-.2(x-.45x) is going to give you the second discount.

anonymous · Answer

putting everything together you will get:
Original price- discounted price-the second discount=final sale price

anonymous · Answer

all you have to do is solve for x
