For example, 0.06(1.25) = 0.075, sof(1.25) = 0.08, since 0.075 is rounded up to 0.08. Use the 6% sales tax functionto find the correct tax on $14.37.The correct tax is Si

Answer 1

We have a sales tax function defined as:

$f(p)=0.06p$

where half cents are rounded to the nearest cent.

We can calculate it for p = 14.37 as:

$f(14.37)=0.06\cdot14.37=0.8622\approx0.86$

In this case, we round down because the third decimal is 2 and is less than 5.

Answer: The correct tax is $0.86.
