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:

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

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

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

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

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

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

$\tt\% \:increase = 6823.53$
