Respuesta :

(A) Because the employer has already deducted 20% to the value of the money, 1,600 is already the 80%. If we let x be value before the deduction, the equation would be,
                                       1,600 = 0.80x
The value of x is $2000. 

(B) We multiply 1/5 by 1,600 giving us an answer of $320.

(C) As an original payment of $2000 be deducted by 8%, the new salary would be $1840. 20% of this value is $368. Therefore, his new paycheck next month will be $1472.2.
