This is the function

Then factor 2 out

Divide both side by two and use the quadratic formula to get the following

X=3 And x=-2 and don't forget to Chek them
Step-by-step explanation:
The original number is x.
The new number is 3x + 5.
We know that 0.5(3x + 5) = 16, so 3x + 5 = 32.
3x + 5 = 32, 3x = 27, x = 9.
Hence the original number is 9.
It would be a total of $19,080
