A university bookstore recently sold a wirebound graphpaper notebook for $0.88, and a collegeruled notebook for $2.38. At the start of spring semester, a combination of 50 of these notebooks were sold for a total of $59.00. How many of each type were sold?

algebra 
Reiny,
number of wirebound  x
number of ruled  50x
solve for x :
.88x + 2.38(50x) = 59
I would multiply by 100
88x + 238(50x) = 5900
etc.
