1000 divided by 10 is a good one, the answer to that problem is 100, and 100 has its first digit in the hundreds place.
Rx + h = sx - k Take all with x to the LHS
Rx - sx = -k - h
x(R - s) = - k -h
x = (-k - h) / (R - s). Multiply top and bottom by -1.
x = (k + h) / (s - R)
Multiply it out
x^2 + 4x -8x -32
Combine like terms
x^2 -4x - 32
It's basically 5,000*2=10,000
and 10,000/2=5,000. your answer would be either they multiplied 5,000 by 2 and 10,000 divided by 2, they increased the sales by 5,000
