To solve this we use the z statistic. The formula for z
score is:
z = (x – u) / s
where x is the sample value = less than 16, u is the
sample mean = 16.1, s is standard dev = 0.1
z = (16 – 16.1) / 0.1
z = - 1
From the standard distribution tables at z = - 1,
P (z = -1) = 0.1587

The given expression can be simplified in many ways by grouping like terms. The simplest form is obtained by factoring out a²b which gives us the following expression.
a²b(7 + 10b +14b²)
Each tube costs $2.25
24.95-6.95=18
18/8=2.25
