a. True
b. False

Answer 1

The formula provided for calculating the total amount of tax, tip, markup, and discount is incorrect.

Step-by-step explanation:

The NEW formulas for calculating the total amount of tax, tip, markup, and discount as presented in the announcement AND my open office hours are: N=0(1+r) and N=O(1-r)a.

The given formulas are incorrect because they involve zero and one as the initial values, which doesn't make sense in the context of tax, tip, markup, and discount calculations.

In mathematics, the correct formulas for calculating tax, tip, markup, and discount would depend on the specific problem and context. Generally, tax can be calculated as a percentage of the original amount, tip can be calculated as a percentage of the total bill, markup can be calculated as a percentage increase in price, and discount can be calculated as a percentage decrease in price.
