Answer:
A+3B=4+5r
Step-by-step explanation:
Given that,
A = 1+r+7r
B = 1-r
We need to find an expression that is equal to A+3B.
Putting the values of A and B in A+3B, we get :
A+3B = 1+r+7r + 3(1-r)
=1+8r+3-3r
=(1+3) +(8r-3r)
=4+5r
Hence, the values of A+3B equals 4+5r.

To the round any figure to the nearest hundred, the 
of the number should be considered. If the number ranges from 1 to 49, it should be rounded to previous hundred, but if the number is between the range of 50 to 99, it should be rounded to the next 100.
Therefore the smallest number when rounded to the nearest 100 that becomes 5000 is 4950
