Thus according to the doctor's recommendation, if the patient needs to cut back 60% of the coffee consumption, then he is only to consume remaining (100-60)= 40% of his daily consumption.

Total daily consumption he can take= 40% of initial consumption

= (40/100) *512 ounces

= 204.8 ounces of coffee

Hence, the patient needs to take only 204.8 ounces of coffee complying by the Doctor’s recommendation.

Evaluate each expression for the given value 2/ 5 - 3 1 /2 for k = 15

Ivahew [28]

Answer:

The value of expression for k = 15 is $\frac{13}{5}$

Step-by-step explanation:

Given expression as :

$\frac{2}{5}$ k - 3 $\frac{2}{5}$

Or, $\frac{2}{5}$ k - 3 - $\frac{2}{5}$

Or, $\frac{2}{5}$ k - $\frac{17}{5}$

Now, for k = 15

The expression is

$\frac{2}{5}$ × 15 - $\frac{17}{5}$

Or, $\frac{30}{5}$ - $\frac{17}{5}$

Or, 6 - $\frac{17}{5}$

Or, $\frac{30-17}{5}$

So, $\frac{13}{5}$

Hence The value of expression for k = 15 is $\frac{13}{5}$ Answer
