Hi there, Could somebody helps me how to set up the equation and find X value out of this question: Natasha has been saving money to buy a new pair of running shoes. The pair she wants cost $188. She currently has $140. She saw an ad in the paper that the store is having a "1/4 off sale''. Does she now have enough money to buy the shoes? if not how much more does she need. If yes, how much will she have left over? thank you

You can write $140 + x = $188(1  1/4), where x is the extra amount she needs (or, if negative, indicates how much will be left over).
