Answer: 62.13%
Step-by-step explanation:
Given , Salary of Mr. Palahniuk = $1190
Percentage of Salary he spent on groceries = 24%=0.24
Amount he deposited in his saving funds = $165
Amount he spent on groceries = (Percentage of Salary he spent on groceries) x (Salary )
= (0.24) (1190)
= $ 285.6
Now , Money left = (Salary) - [(Amount he deposited in his saving funds)+(Amount he spent on groceries)]
= $1190-[$285.6+$165]
= $1190 - $450.6
=$739.4
Percentage of his salary is left = (Money left )÷ (Salary) x 100
= (739.4) ÷(1190) x 100
≈62.13%
Hence, the percentage of his salary is left = 62.13%
