Subtract to find the amount of the discount:
80.00 - 60.00 = 20.00
Divide the amount of discount by original price:
20.00 / 80.00 = 0.25
Multiply by 100 to get percent:
0.25 x 100 = 25%
Answer: 25%
Z = ( X - Mean ) / SD
z = ( 646 - 597 ) / 39
z = 49/39 = 1.25
With the z-score table:
for z = 1.25, p = 0.8944 ( probability that the cost will be lower than $646 )
1 - 0.8944 = 0.1056
