miss Akunina [59]

Let the original bill be $x$ , then the final bill after the charges been added are $1.2x+25$ , where $1.2$ is the increase in the bill by 0.2 (100%+20% = 120% = 1.2)

The range of the original bill is
200 < $1.2x+25$ < 800, subtract each term by 25
175 < $1.2x$ < 775, divide each term by $1.2$
145.83 < $x$ < 645.83

Hence, the range of the original bill is between $145.83 and $645.83
