Answer:
X ≥ 112,6 $
Step-by-step explanation:
Normal Distribution N ( 95 , 16 )
μ₀ = 95
σ = 16
We need to get z (score) for area 0,1357; then from z - Table we get
z (score) = 1,1
Now z (score ) = ( X - μ₀ )/σ
1,1 = ( X - 95 ) / 16
17,60 + 95 = X
X = 112,6 $
That means that in order to get a gift customes has to spend at least 112,6 $
