Answer:

The percentage of milk in the resulting mixture is 19.44% and this can be determined by using the unitary method.

Given :

Dishita 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:

=\dfrac{18}{100}\times 10=

100

18

×10

= 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:

=\dfrac{3.5}{1.8}\times 10=

1.8

3.5

×10

= 19.44 %

The percentage of milk in the resulting mixture is 19.44%.

Answer:

Required percentage of milk in the resulting mixture is 19%.

Step-by-step explanation:

Given, 18 oz cup of coffee has 10% milk.

We know,

x\% \: of \: y =  \frac{x}{100}  \times y

So, quantity of milk = 10% of 18 oz

 =  \frac{10}{100}  \times 18 \\  = 1.8 \: oz

Again,it is also given that Dishita adds 2 oz of milk

So, quantity of total coffee  = (18 + 2) = 20 \: oz

and quantity of milk in 20 oz coffee  = (2 + 1.8) = 3.8 \: oz

Here 20 oz means 100%

So, 1 oz means  \frac{100}{20}  \%

3.8 oz means

 \frac{100}{20}  \times 3.8 \\  = 19\%

Therefore, required percentage of milk in the resulting mixture is 19%.

This is a problem of percentage.
