Question 1072588
 A candy maker mixed marshmallows worth $1.80 a pound with rice crispies worth $3.20 a pound to make 50 pounds of a rice crispie treats worth $2.92 a pound. Find the number of pounds of each item used. 
----
weight:: m + r = 50 lbs
Value:::1.8m+3.2r = 2.92*50
---------------------------------
1.8m + 3.2(50-m) = 147.5
1.8m + 160 - 3.2m = 147.5
1.4m = 12.5
m = 8.93 lbs (amt. of marshmallows needed)
r = 41.07 lbs (amt. of rice crispies)
