Let = cups of olive oil she should add
will be the cups of oil in vinaigrette
is the total cups in recipe
I can say:

She needs to add 8 cups of oil
---------------------------
Let = total cost
You need to know { ounces / cup ). When you
have that, make the conversions:
cost of oil: ( 40 cents / ounce ) x ( ounces / cup ) x ( 9 cups ) = cents
cost of vinegar: ( 25 cents / ounce ) x ( ounces / cup ) x ( 3 cups ) = cents
Add them to find , total cost
