John's gross monthly salary is $2000.
John receives a 15% raise in his salary.
So first we have to find 15% of $2000.
15% of 2000 = [tex] (2000)(\frac{15}{100})[/tex]
= [tex] \frac{(2000)(15)}{100}[/tex]
= [tex] \frac{30000}{100}[/tex]
= [tex] 300[/tex]
John's salary including the raise = $[tex] (2000+300) [/tex] = $2300.
Now 30% of his monthly paycheck withheld for taxes.
30% of 2300 = [tex] (2300)(\frac{30}{100})[/tex]
= [tex] \frac{(2300)(30)}{100}[/tex]
= [tex] \frac{69000}{100}[/tex]
= [tex] 690[/tex]
So the amount of tax deducted = $690.
John's net monthly income = $ [tex] (2300-690) [/tex] = $1610.
So we have got the required answer.
