sal and thomas went to the mall to buy games for their xboxes. Thomas had $5 less than sal had. Together they have $43. If the used games they were considering buying were $20 (including sales tax),can both of tem buy games with their own money ? Why or why not ?
Sal has x
Tom has x-5
2x - 5 = 43
2x = 48
x = 24
Sal had 24 and Tom had 19
Make use of that information to answer the question.
