Answer: [tex]13\ ml[/tex]
Step-by-step explanation:
Let be "x" the amount of milliliters of sunscreen Yoku needs to conver [tex]325\ cm^2[/tex] of his skin.
In order to get the solution of this exercise it is important to analize the information given in the exercise.
You know that Yoku uses [tex]2\ ml[/tex] to cover an area of [tex]50\ cm^2[/tex] of his skin, so, with this data you can set up the following proportion:
[tex]\frac{50}{2}=\frac{325}{x}[/tex]
Then, the final step is to solve for "x" in order to find its value. This is:
[tex](x)(\frac{50}{2})=325\\\\x=(325)(\frac{2}{50})\\\\x=13[/tex]
