x = lbs of the type of chocolate that sells for $1.60/lb
y = lbs of the type of chocolate that sells for $4.70/lb
You would like to have 15.5 lbs of a chocolate mixture that sells for $1.80/lb
x + y = 15.5
1.60x + 4.70y = 1.80*15.5
by solving the above system of equations we find:
x = 14.5 lbs
y = 1 lbs
