Yolanda's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Yolanda $5.20 per pound, and type B coffee costs $4.05 perpound. This month, Yolanda made 130 pounds of the blend, for a total cost of $586.30. How many pounds of type B coffee did she use?
+37146 B = pounds of B
A = pounds of A which equals 130 - B
5.20 (130-B) + (B) 4.05 = (586.3) solve for B
