Question

An advertisement says that during a sale you can at least save $50 on a suit. The most expensive suit sold for $249 during the sale. How much did the suit sell for before the sale?

Answer 1

Let x be the cost before the sale, since during the sale you can at least save $50, the cost before the sale was

$x\ge\text{ \ 249+\ 50}$

Therefore, the suit cost before the sale was

$x\ge\text{ \ 299}$

that is, it costs greater or equal to $299
