Question

How do you find the cost per ounce of a mixture of 200 oz of a cologne that costs $5.50 per ounce and 500 oz of a cologne that costs $2.00 per ounce?

Answer 1

Cost per OZ of the Mixer `=$3`

Explanation:

Total Cost of 200 oz of a cologne that costs $5.50 per ounce `=200 xx 5.50 = $1100`
Total Cost of 500 oz of a cologne that costs $2.00 per ounce `=500 xx 2.00=$1000`

Cost per OZ of the Mixer `=(1100+1000) / (200+500)=2100/700=$3`
