<PRE><B>Question 153066</B>
7,000+7.5x=8,800+6(1,500-x)
7,000+7.5x=8,800+9,000-6x
7.5x+6x=17,800-7,000
13.5x=10,800
x=10,800/13.5
x=800 for the # of calculators made @ the Exton plant.
1,500-800=700 for the # of calculators made @ the Whyton plant.
proof:
7,000+7.5*800=8,800+6*700
7,000+6,000=8,800+4,200
13,000=13,000
