Chapter 7, Problem 38P

Repeat parts (a)—(d) of problem P7-37 if Composite A requires 1.6 pounds of carbon fiber and 0.5 ounces of polymer resin while Composite R requires 1.75 Pounds of carbon fiber and 0.78 ounces of polymer resin. If the available quantities of carbon fiber and resin are 17 pounds and 12 ounces, respectively, the amount of each composite to manufacture satisfies the system of equations (7.150) and (7.151).

$0.16x_A+2.5x_B=17$ $(7.150)$ $0.16x_A+2.5x_B=17$. $(7.151)$
