Given :
John adds 2 oz of milk to an 18 oz cup of coffee that is 10% milk.
The following steps can be used to determine the percentage of milk in the resulting mixture:
Step 1 - The unitary method can be used to determine the percentage of milk in the resulting mixture.
Step 2 - Given that 18 oz cup of coffee has 10% of the milk that is:
[tex]=\dfrac{18}{100}\times 10[/tex]
= 1.8 oz of milk
So, the 18 oz cup of coffee contains 1.8 oz of milk.
Step 3 - It is given that 2 oz of milk is added in 18 oz cup of coffee. So, the total mixture becomes 20 oz.
Step 4 - So, an 20 oz cup of coffee there 3.5 oz of milk.
Step 5 - If 1.8 oz is 10% then 3.5 oz is:
[tex]=\dfrac{3.5}{1.8}\times 10[/tex]
= 19.44 %
The percentage of milk in the resulting mixture is 19.44%.
