A sporting goods store sells right-handed and left-handed baseball gloves. In one month, 12 gloves were sold for total revenue of $561. Right-handed gloves cost $45 and left-handed gloves cost $52. Howmany of each type of glove did they sell?
----------------
Let # of right-handed gloves sold be "x"; value is 45x dollars
--------
# of left-handed gloves sold will be 12-x; value is 52(12-x)=624-52x dollars
--------------
EQUATION:
value + value = 561
45x + 624-52x = 561
-7x = -63
x=9 (# of right-handed gloves sold)
12-9 = 3 (# of left-handed gloves sold)
