King Street Printing recently charged 1.9 cents per sheet of paper, but 2.4 cents per sheet for paper made of recycled fibers. Darren's bill for 150 sheets of paper was $3.41. How many sheets of each type were used?
---------------------
Let number of regular sheets be "x" ; value of these is 1.9x cents
---------------------------
# of recycled sheets is "150-x" ; value is 2.4(150-x)=360-2.4x cents
----------------------------
EQUATIONS:
value + value = 341 cents
1.9x + 360-2.4x = 341
-0.5x = -19
x = 38 (# of sheets of regular paper)
150-x = 112 (# of sheets of recycled paper)
