The original number is 85.2
Step-by-step explanation:
we can represent this in an equation where the initial value is going to be and to this we will subtract 2.6% of it
x - x * 2.6/100 = 83
x - 0.026x = 83
0.974x = 83
x = 83 / 0.974
x = 85.2156
we round to the nearest tenth and finally we get that the result is 85.2
if we want to verify that it is ok we can replace the x with the value of 85.2156 and we should have the same number on each side of the equality
