Cherokee · Answer 1

I believe it is

z-0.10 (z) = 253.10

Atticus Medina · Answer 2

The price of the stoke is denoted with Z.

Alana's total cost with the price dropped included is $253.10. This means that we can write the equation:

total cost with the price drooped=price of the stock before the price dropped - the dropped price

$253.10=Z-0.10 (Z)

or, rewritten:

D.) z-0.10 (z) = 253.10
