X+8=b
x-12=s
X+b+s=50 then
x+x+8+x-12=50
So 3x-4=50
Then 3x=54
So x=18
Then the brother is 26 and the sister is 6
Check 26+18+6=50

Weiming receives a weekly pocket money of $28. If he decides to save 20% of it, find his saving in a year and spendings in a yea
Maru [420]

Welming's spending is $1164.8 and his savings is $291.2

<h3>How to determine the savings and the spending?</h3>

The given parameters are:

Weekly pocket = $28

Save = 20%

There are 52 weeks in a year.

So, the yearly pocket is:

Yearly pocket = $28 * 52

Evaluate

Yearly pocket = $1456

He saves 20%.

So, we have:

Savings = 20% * $1456

Evaluate

Savings = $291.2

His spending is then calculated as:

Spending = $1456 - $291.2

Evaluate

Spending = $1164.8

Hence, Welming's spending is $1164.8 and his savings is $291.2
