Answer 2

Answer:

in order to solve this we must find out how many ounces there are in total which is 1, because 4 *(1/4) gives me the amount of that i have since it is 1/4 ounces per pump.

Now if you set up the ounces and price as a ratio of cost to ounce you can get the cost per ounce. This is done by setting up the ratio as 8.29(cost)/25.36(counces). You then divide 25.36(ounces) to get one ounce and divide 8.29 by 25.36 to get the cost per ounce (8.29(cost)/25.26)/ (25.36(ounces)/25.36).

this gives us roughly .33(cost)/1(ounces). We have 1 ounce so this means that it is 33 cents per ounce.
