Answer:
$82.65
Step-by-step explanation:
First, find the cost with the discount:
78.72(0.85)
= 66.91
Then, find the amount of the tip:
78.72(0.2)
= 15.74
Then, add together the cost and tip:
66.91 + 15.74
= 82.65
So, the total cost of the meal was $82.65
You would need to pay 15.75. 5% is 0.05, so 15 times 0.05 is .75.
Answer:
x=2, y=1
x=-2, y = -1
Step-by-step explanation:
x - 2y = 0
x = 2y
x² - y² = 3
(2y)² - y² = 3
3y² = 3
y² = 1
y = 1 or y = - 1
x = 2 or x = -2
The patient should drink 3000 milliliter per day
<em><u>Solution:</u></em>
Given that a patient is told to force fluids to 3 liter per day
To find: Amount the patient should drink in milliliter
Use the conversion factor,
1 liter = 1000 milliliter
Now we have to find the amount the patient she drink in milliliter
Amount patient drinks in liter = 3 liter per day
Therefore, convert 3 liter to milliliter
3 liter = 1000 x 3 milliliter = 3000 milliliter
Thus the patient should drink 3000 milliliter per day
