\boldsymbol{\mathbf{4 ounces water we need to add.}}
An after shave lotion contains 45% of ethyl alcohol
i.e 100% - 45% = 65% nonalcoholic
As mentioned, we have 8 ounces of fluid and that contains 45% of ethyl alcohol.
i.e
We need fluid which 70% nonalcoholic.
i.e 100 - 70 = 30% of alcohol.
Then there is already 3.6 ounces of alcohol in fluid.
As required, Let consider 3.6 ounce is 30% of alcohol.
70% must be other liquid.
That is equal to =
=
= 8.4 Ounces Of other liquid.
Then total ounces of the lotion is
= 3.6 + 8.4
= 12 ounces.
Water required to add is,
= 12 - 8
=

PQ and QR are congruent (given)
QS and SQ are congruent (Reflexive Property)
∠PQS and ∠RQS are congruent (again, Reflexive Property)
Note: It is not SSS, becase we do not have the information (yet) to state that PS is congruent with RS
hope this helps
