$\huge\mathcal{Heya!}$

Here's your answer⤵️⤵️⤵️

$\orange{ \tt: { \therefore{price \: of \: computer \: after \: 6th \: year = £1977.1}}}$

$\green{\underline \bold{given :}}\\ \tt :\implies \: price \: of \: computer = 2100 \\ \\ \tt: \implies depreciate \:rate\%= 1\\\ \\ \red{\underline \bold{to \: find}} \\ \tt: \implies price \: of \: computer \: after \: 6 \: year$

●According to the question

$\bold{as \: we \: know \: that :} \\ \tt: \implies 1st \: year \: depreciate \: price = 2100 - 2100 \: of \: 1\% \\ \\ \tt: \implies 1st \: year \: depreciate \: price = 2100 - 2100 \times \frac{1}{100} \\ \\ \tt: \implies 1st \: year \: depreciate \: price = 2100 - 21 \\ \\ \tt: \implies 1st \: year \: depreciate \: price = £2079 \\ \\ \bold{for \: 2nd \: year : } \tt: \implies 2nd \: year \: depreciate \: price = 2079 - 1\% \: of \: 2079 \\ \\ \tt: \implies 2nd \: year \: depreciate \: price = 1977.1083077421 \\ \\ \green {\tt: \implies 6th\: year \: depreciate \: price = £1977.1}$
