For some value of z, the value of the cumulative standardized normal distribution is 0.8340. the value of z is
Answer: We are required to find the value of z corresponding to probability 0.8340.
i.e., 
We can find the value of z using the standard normal table.
Using the standard normal table, we have:

Therefore, for the value of z = 0.97, cumulative standardized normal distribution is 0.8340
Attached here standard normal table for your reference.
Let x be the original price. The discount on this item is 64% of x, that means:
discount = x(0.64) = $30, x = 30/0.64 = original price x = $46.875:
Write an equation:
NET PRICE = Original price - discount (on the original price)
NET PRICE = x - 0.64.x or NET PRICE = x(1-0.64)
NET PRICE =0.36.x
W ÷ 9 = 9
w = 9 × 9
w = 81
