Answer:
No her calculations do not make sense because the area of the smaller walls together is 234 and not 244 the total square feet of the windows and doors are also wrong. She should also subtract the doors and windows from the total so she doesn't over spend on paint. Her answer is correct just the way of finding it is wrong.
Step-by-step explanation:
Walls total sqft: (2(13ft)(9ft))+(2(16ft)(9ft))=234ft²+288ft²=522ft²
Doors+Windows total sqft: ((2(20ft)+(2(15ft))=60ft²+30ft²=90ft²
Total amount of paint needed: 522ft²-90ft²=432ft²
Amount of gallons needed remains the same
Hopefully this makes sense.

Answer:
The graph in the attached figure
Step-by-step explanation:
we have
Using a graphing tool
see the attached figure
This is the equation of a vertical parabola open downward
The vertex is the point (3.25,225) (a maximum)
The zero's of the function or the t-intercepts are the points (-0.5,0) and (7,0)
The h-intercept of the function is the point (0,56)
The domain of the function are all real numbers
The range of the function 
----> All real numbers less than or equal to 225
Answer:
<h3>
100.375</h3>
Step-by-step explanation:
so 110
110/100=1.1
*15
16.5
16.5 dollar coupon
ok then sales tax
1.1*6.25
6.875
sales tax is 6.875
110-16.5
93.5
93.5+sales tax 6.875
100.375
final price 100.375
hope this helps!!
