At the start of spring semester, a combination of 50 of these notebooks were sold for a total of $118.60. How many of each type were sold? Answer by checkley71(8403) (Show Source):
You can put this solution on YOUR website! (50-X)2.50+2.3X=118.60 OR 125-2.5X+2.3X=118.60 OR -.2X=-6.40 OR X=6.40/.2 OR
X=32 BOOKS THAT SOLD FOR $2.30 AND THE REMAINDER (50-32=18) SOLD FOR $2.50 OR $45.00 THUS 32*$2.30 = $73.60 & $45.00 = $ 118.60
