10% off of 199.99 is 179.99
100% - 10% = 90% The 90% is how much you are going to pay. 
90% into decimal form is 0.9
So you can do 199.99 x 0.9 = $179.99

Answer:  126</h3>
=====================================================
Work Shown:
Let x and y be the two numbers.
We're given x = 162 and the variable y is unknown.
We're also given LCM = 1134 and HCF = 18
So,
LCM = (x*y)/HCF
1134 = 162*y/18
1134 = (162/18)y
1134 = 9y
9y = 1134
y = 1134/9
y = 126
The other number is 126
---------------------
Notice that
showing that 18 is the highest common factor (HCF) of the numbers 162 and 126. This partially confirms the answer.
Now let,
- A = multiples of 162
- B = multiples of 126
So,
- A = 162, 324, 486, 648, 810, 972, 1134, 1296, ...
- B = 126, 252, 378, 504, 630, 756, 882, 1008, 1134, 1260, ...
We see that 1134 is in each list of multiples and the smallest such common item. So the lowest common multiple (LCM) of 162 and 126 is 1134. This helps fully confirm the answer.

Step-by-step explanation:
 
        
             
        
        
        
First we need to find the volume of the closet
V=l*w*h
V=3*3*7
V=3*21
So the volume is 63
Since 67 cubic feet is larger than 63 cubic feet, the boxes won't fit
Hope this helps
