ខ្ញុំចង់សួរថាតើមានឧទារហ៍ពីរបៀបគិតលុយពីការងារថែមម៉ោងដែរទេ?
ឧទារហ៍ៈ ប្រាក់ខែគោល200ដុល្លា ធ្វើការងារថែមម៉ោងបាន ៣៥ម៉ោង និង ១៥ម៉ចំពោះថ្ងៃអាទិត្យ។
សូមជួយបង្ហាញពីរបៀបនៃការគិតផង អរគុណ
សម្រាប់ការងារបន្ថែមម៉ោងថ្ងៃធម្មតាដែលធ្វើពេលថ្ងៃ៖ ប្រាក់ឈ្នួលគោលប្រចាំថ្ងៃ x ១,៥
ការងារបន្ថែមម៉ោងថ្ងៃធម្មតាដែលធ្វើពេលយប់ (ពីម៉ោង ១០ យប់ ដល់ម៉ោង ៥ ភ្លឺ)៖ ប្រាក់ឈ្នួលគោលប្រចាំថ្ងៃ x ២
ការងារបន្ថែមម៉ោងថ្ងៃអាទិត្យ និងថ្ងៃបុណ្យ៖ ប្រាក់ឈ្នួលគោលប្រចាំថ្ងៃ x ២
ការងារបន្ថែមម៉ោងថ្ងៃបុណ្យ៖ ប្រាក់ឈ្នួលគោលប្រចាំថ្ងៃ x ២
២០០/(២៦*៨)=០,៩៦១ដុល្លារ/ម៉
=> ១,៤៤១៥ ដុល្លារ/ម៉ សម្រាប់ការងារថែមម៉ោងថ្ងៃធម្មតាវេណថ្មី
=> ១,៩២២ ដុល្លារ/ម៉ សម្រាប់ការងារបន្ថែមម៉ោងថ្ងៃអាទិត្យ ថ្ងៃបុណ្យនិងថែមម៉ោងពេលយប់
៣៥ម៉ោង x ១,៤៤១៥ដុល្លារ/ម៉ = ៥០,៤៥២៥ ដុល្លារ (សម្រាប់ការបន្ថែមម៉ោងធម្មតា)
១៥ម៉ោង x ១,៩២២ ដុល្លារ/ម៉ = ២៨,៨៣ ដុល្លារ សម្រាប់ការងារថែមម៉ោងថ្ងៃអាទិត្យ
តែសូមប្រាប់ថាថែមម៉ោងច្រើនយ៉ាងនេះ គឺខុសច្បាប់ការងារហើយ!
