45.50(original price) * .8 (discount) * 1.05 (tax) =$38.22(final answer)
4 Standard drinks he has consumed in over a two - hour time period.
<h3>What is Unitary Method?</h3>
The unitary method is a method in which you find the value of a unit and then the value of a required number of units.
For example: 5 cars have price of $500. what will be the price of 10 cars.
Now, we know
5 cars → $500
1 car → $500/5
1 car → $100
10 cars → 8 x $100
10 cars → $800
The standard drink contains 12 - ounce of beer.
Here, we have given 1 red cup which has 16 - ounce of beer.
He has 3 red cups.
So, total ounce of beer he has consumed in two hour time period:
16 x 3 = 48 ounce of beer.
Now, as we know standard drink contains 12 - ounce of beer.
so, Number of standard drink = 48/12 = 4
Hence, 4 Standard drinks he has consumed in over a two - hour time period.

Answer:
1x-1y
Step-by-step explanation:
-----------------------------------------------
Information Given:
-----------------------------------------------
ON = 7x - 9
LM = 6x + 4
MN = x - 7
OL = 2y - 7
-----------------------------------------------
Since it is a parallelogram:
-----------------------------------------------
ON = LM and
MN = OL
-----------------------------------------------
ON = LM:
-----------------------------------------------
7x - 9 = 6x + 4
-----------------------------------------------
Subtract 6x from both sides:
-----------------------------------------------
x - 9 = 4
-----------------------------------------------
Add 9 to both sides:
-----------------------------------------------
x = 13
-----------------------------------------------
MN = OL:
-----------------------------------------------
x - 7 = 2y - 7
-----------------------------------------------
Sub x = 13:
-----------------------------------------------
13 - 7 = 2y - 7
-----------------------------------------------
Simplify:
-----------------------------------------------
6 = 2y - 7
-----------------------------------------------
Add 7 on both sides:
-----------------------------------------------
13 = 2y
-----------------------------------------------
Divide by 2:
-----------------------------------------------
y = 13/2
-----------------------------------------------
Answer: x = 13, y = 13/2 (Answer D)
-----------------------------------------------
