) of $61,000 and a standard  deviation(
) of $23,000.
denoted the profit.
be the minimum profit required to have a party.
![\Rightarrow\ P(\dfrac{x-\mu}{\sigma}\dfrac{x_0-61000}{23000})=0.05\\\\\Rightarrow\ P(z\dfrac{x_0-61000}{23000})=0.05\ \ \ [z=\dfrac{x-\mu}{\sigma}]\\\\\Rightarrow\ \dfrac{x_0-61000}{23000}=1.645\ \ [\text{critical z-value for p-value 0.05=1.645}]\\\\\Rightarrow\ x_0-61000 =1.645\times 23000\\\\\Rightarrow\ x_0-61000 =37835\\\\\Rightarrow\ x_0=37835+61000\\\\\Rightarrow\ x_0=98835](/tpl/images/0818/5805/a3c47.png)
