Question

3.Solve each percent problem
30) There are 18 boys and 46 girls in a class 87.5% of the students in the class take the bus to school. How many students do not take the bus to school? _​

Answer 1

$Given \: Number \: boys \: in \:a\:class = 18$

$Number \: girls \: in \:the\:class = 46$

$\blue{ Total \: students \: in \:the \:class}$

$= number \: of \:girls + number \:of \:boys$

$= 18 + 46$

$= 64$

$Number \:of \: students \: who \:take \:bus =87.5\% \: of \: (Total \: students)$

$Number \:of \: students \: who\: do \:not$

$take \:bus = ( 100 - 87.5)\% \times (Total \: students )$

$= 12.5\%\times 64$

$= \frac{12.5}{100} \times 64$

$= \frac{800}{100}$

$= 8$

Therefore.,

$\red{Number \:of \: students \: who\: do \:not}$

$\red{take \:bus } \green { = 8 }$
