 Question 585108: Ok so here is my word problem: A university bookstore recently sold a wirebound graph-paper notebook for \$1.64, and a college-ruled notebook for \$1.17. At the start of spring semester, a combination of 50 of these notebooks were sold for a total of \$66.02. How many of each type were sold? So far what I have is: x+y=50 1.64x+1.17y=66.02 I found that x=50-y but now I am completely lost. Please help. Thanks in advance.Answer by Alan3354(30993)   (Show Source): You can put this solution on YOUR website!A university bookstore recently sold a wirebound graph-paper notebook for \$1.64, and a college-ruled notebook for \$1.17.

Sub for x in the 2nd equation 1.64x+1.17y=66.02 Eliminate fractions first 164x+117y=6602 164*(50-y) + 117y = 6602 8200 - 164y + 117y = 6602 -47y = - 1598 y = 34 = 34 college-ruled, whatever that is. ----------- x = 50-y = 16 graph-paper thingies
