Solve the problem.A department store is having a clearance sale. The price on a television is reduced by 27%. That sale price is then reduced by another 27%. If x is the television's original price, the sale price can be represented by (x - 0.27x) - 0.27(x - 0.27x). With these two reductions, at what percentage of the original price is the television being sold? Use the factored, simplified form of the expression to answer the question.
