Write the Expression with Only Positive Exponents and Evaluate If $$\frac { 5 } { 4 } ( 16 y - 16 x + 20 z )$$

Write the expression with only positive exponents and evaluate if possible. Assume all variables represent nonzero real
numbers.

A) $20 y - 20 x - 25 z$
B) $20 y + 20 x + 25 z$
C) $20 y + 20 x - 25 z$
D) $20 y - 20 x + 25 z$
