Question 439694
<font face="Times New Roman" size="+2">


Let *[tex \Large x] represent the cost of the toy.  Then *[tex \Large 0.07x\ =\ 0.18], hence *[tex \Large x\ =\ 2.57]  so he paid *[tex \Large 2.57\ +\ 0.18\ =\ 2.75] for the toy ball.  So he paid *[tex \Large 5.15\ -\ 2.75\ =\ 2.40] for one grapefruit.  Therefore, your problem is incorrectly worded.  Instead of <i>A man goes into a grocery store</i> it should be <i>An idiot goes into a grocery store</i>, unless maybe he is in Tokyo where the prices are sky high for citrus AND he bought 2 grapefruit.

My calculator said it, I believe it, that settles it
