A Cat-Food Company makes a special kind of cat food. It consist of 40% meat powder and 60% grain. The meat powder costs $1.20 per pound. The grain costs 80 cents per pound. What is the cost of the raw materials per pound of cat food?

Work with the "weighted mean".

For each pound,
cost of meat powder = 0.4*1.20 = 0.48
cost of grain = 0.6*0.80 = 0.48
Total cost per pound = 0.48+0.48 = $0.96
