Question 7228
They sold 5 times more batteries than pens. 
Then pens=x and batteries=5x


When setting up the equation, make sure you read through it carefully. 


the pens were $5 each and the batteries were $3 each. 
so:  $5(x) + $3(5x)=$960


5x+15x=960
20x=960


{{{20x/20}}}={{{960/20}}}
x=48
5x=240


*********They sold 48 boxes of pens and 240 boxes of batteries.********* 





CHECK:  
48x5=240
240x3=720

240+720=960
