A computer company’s featured laptop cost $800 last year. This year [#permalink] ### Show Tags 07 Mar 2019, 00:28 Since the laptop costs$800 last year and it costs 15% less this year, it will cost $680($$\frac{17}{20}*800$$) Next year, the laptop will cost $$\frac{5}{4}*680$$ =$850(Option D)

P.S It helps if you remember the common percentage to fraction conversions.

$$\frac{100-15}{100} = \frac{85}{100} = \frac{17}{20}$$

$$\frac{100+25}{100} = \frac{125}{100} = \frac{5}{4}$$
