Find the percent increase. Round to the nearest percent. From 85 books to 143 books The percent increase is​
klasskru [66]

We are given :

  • Initial = 86
  • Final = 143

Let's find the percent increase with the help of formula:

\boxed{ \sf \: formula : 100 \times  \frac{(final - initial)}{initial} }

\red{ \rule{35pt}{2pt}} \orange{ \rule{35pt}{2pt}} \color{yellow}{ \rule{35pt} {2pt}} \green{ \rule{35pt} {2pt}} \blue{ \rule{35pt} {2pt}} \purple{ \rule{35pt} {2pt}}

\tt \% \: increase =  100 \times \frac{(143 - 85)}{85}

\tt  \% \: increase = 100 \times  \frac{58}{85}

\tt\% \: increase = 20 \times   \frac{58}{17}

\tt\% \: increase =  \frac{1160}{17}

\tt\% \:increase = 6823.53
