Question

Michael receives a weekly pocket money of $28. If he decides to save 20% of it, find his saving in a year and spending in a year

Answer 1

           $Saving$ $in$ $a$ $year$$=\ 292$

       $Spending$ $in$ $a$ $year$$=\ 1168$

Step-by-step explanation:

Given,

$Michael$ $weekly$ $pocket$ $money$$=\ 28$

$Michael$ $yearly$ $money$$=\ 28\times 365/7$

                                    $=\ 1460$

$He$ $decides$  $to$ $saving$ $20$% $of$ $it$

$Saving$ $in$ $a$ $year$$=1460\times 20%$%

                          $=1460\times 20/100$

                          $=\ 292$

$Spending$ $in$ $a$ $year$  $=\ 1460-\ 292$

                                $=\ 1168$

Answer 2

$\fontsize{18}{10}{\textup{\textbf{Savings : 67.2 dollars ; spending : 268.8 dollars}}}$

Step-by-step explanation:

Weekly pocket money of Michael = $28.

So, the annual pocket money of Michael is given by

$A_m=\ (28\times12)=\ 336.$

Since Michael saves 20% of his pocket money, so the savings in one year is

$A_s=20\%\times A_m=\dfrac{20}{100}\times336=\ \dfrac{336}{5}=\ 67.2.$

And, spending in one year is given by

$A_{sp}=A_m-A_s=336-67.2=268.8.$

Thus, required savings in a year is $67.2 and spending  in a year is $268.8.
