Question 1048844
<font face="Times New Roman" size="+2">


On the day before the last day of the sale, the price of the sofa was *[tex \Large 0.7\ \times\ 290].  Then, on the last day of the sale, the price was again reduced to 80% of the price the day before, so


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 0.8\left(0.7\ \times\ 290)\ =\ 0.56(290)]


You can finish the arithmetic yourself.
