Hi!
3.28$ = 328 cents
8 1/5 ounces = 41/5 ounces
We will find the unit cost, cents per ounce, using proportions, like this:
328 cents for 41/5 ounces
x cents for 1 ounce
________________________
x = (328*1)/(41/5)
x = 328/(41/5)
x = (328*5)/41
x = 1640/41
x = 40
Unit cost = 40 cents per ounce.
Hope this helps!
