Answer:
1.15p + 285 = 5.84
Step-by-step explanation:
This problem has two equations. Total cost and Total pounds. The cost and the pounds
p = apple pounds
b = banana pounds
<u>Cost</u>
1.90p + .75b = 5.84
<u>Pounds</u>
p + b = 3.8
<u>Now we use the substitute method for system of equations to solve</u>
p + b = 3.8
b = -p + 3.8
<u>Now that we know what b equals, substitute is for b in the cost equation.</u>
1.90p + .75b = 5.84
1.90p + .75(-p+3.8) = 5.84
<u>distribute / multiply .75 by (-p+3.8)</u>
1.90p + -.75p + 2.85 = 5.84
<u>Combine the p values</u>
1.15p + 285 = 5.84
So you divide by 2 because there is 2 buildings. You get 760. Now, just take 200 away from one building, and 200 away from the other, and you get 560 for Building A, and 960 from Building B.
It is a very simple problem, if you know the way for representing it in a proper manner. There are basically no complications associated with this problem.

I hope the procedure is simple enough for you to understand. I also hope that this is the answer that you were looking for and the answer has actually come to your desired help.
L=3W, H=2L, so H=6W
Since W=7, the dimensions would be:
W=7in, L=21in, H=42in
The surface area of any rectangular prism is:
A=2(LW+LH+WH), and since W=7, L=21, H=42
A=2(21*7+21*42+7*42)
A=2(147+882+294)
A=2(1323)
A=2646 in^2
The volume would be:
V=LWH, since L=21, W=7, H=42
V=21*7*42
V=6174 in^3
You question didn't really specify what you were looking for, so I did the best I could, if you need more info, just ask in the comments. :)
Number of pennies:P
Number of nickels:N
Number of dollar bills:D
P=N+12
N=D+5
1P+5N+100D=996
^given
Therefore
P=(D+5)+12
P=D+17
Plug back into main equation
(D+17)+5(D+5)+100D=996
Combine like terms
106D+42=996
106D=954
D=954/106=9
9 Dollar bills
N=D+5
N=(9)+5=14
14 Nickels
P=N+12
P=(14)+12=26
26 Pennies
26*1+14*5+9*100=996
Final answer:
9 Dollars
14 Nickels
26 Pennies
