Kelly has 4x as much money as Joey. After Kelly uses some money to buy a racquet, and Joey uses $30 to buy shorts, Kelly has twice as much money as Joey. If Joey started with $98, how much money does Kelly have? what does the racquet cost?

Step 1 As Joey started with $98 and Kelly had 4 times as much money as Joey had, Kelly started with 98*4=$392 Assume that racquet costs $x, so Kelly will be left with $392-$x=$(392-x) As Joey spent $30 to buy shorts, he was left with $98-$30=$68 Now Kelley has $(392-x) and Joey has 68, as Kelly has twice as much money as Joey has, we have 392-x=2*68 or 392-x=136 or 392-x+x=136+x or 136+x=392 or x=392-136=256 So Kelley has $136 and racquet costs $256
