Ronni has a bottle of peroxide that states it is 70% peroxide. If the bottle contains 16 ounces, how many ounces are not peroxide? Round your answer to the nearest tenth.
A.4.8 ounces B.5.0 ounces C. 1.1 ounces D. 11.2 ounces
Since the bottle contains 70% peroxide, the remaining 30% must be something other than peroxide.
To find out how many ounces are not peroxide, we multiply the total number of ounces (16) by the percentage of the substance that is not peroxide (30%).
Not peroxide = 16 x 0.30 = 4.8
Therefore, there are 4.8 ounces of substance that are not peroxide.
Round to the nearest tenth, the answer is A. 4.8 ounces.
