What is percentage ?

In mathematics, a percentage is a number or ratio spoken as a fraction of 100. It is often indicated by the percent sign '%', but the abbreviations 'pct.', 'pct', and 'pc' are also sometimes used. Percentages are dimensionless numbers. No units of measure

Calculation

825 + 8.25x = 870

8.25x = 870 - 825

x = 45/8.25

x = 5.454545454545455 %

x = 5.5 % (rounded to nearest tenth)
