<PRE><B>Question 209251</B>
Find the cost per ounce of a sunscreen made from 100 oz. of a lotion that costs $2.50 per ounce and 50 oz. of a lotion that costs $4.00 per ounce
--------------------------------------------
Total Value: 2.5*100 + 50*4 = 250 + 200 = $450
Total Weight: 100 + 50 = 150 oz
-------------------------------------
Cost per ounce = 450/150 = $3
=====================================
Cheers,
Stan H.
