We are given:

\mu=247,\sigma=60

We need to find the z scores for the following vacation expense amounts:

$197, $277, $310

We know that z score formula is:

z=\frac{x-\mu}{\sigma}

When x = 197, the z score is:

z=\frac{197-247}{60}

        =\frac{-50}{60}

        =-0.83

When x = 277, the z score is:

z=\frac{277-247}{60}

        =\frac{30}{60}

        =0.5

When x = 310, the z score is:

z=\frac{310-247}{60}

        =\frac{63}{60}

        =1.05

Therefore, the z scores for the vacation expense amounts $197 per day, $277 per day, and $310 per day are -0.83, 0.5 and 1.05 respectively
