Final answer:

The correct expression for multiplying 80 by 24 and then subtracting one group of 24 is (80 * 24) - 24, which is represented here as Option A.

Step-by-step explanation:

The expression for multiplying 80 by 24 and then subtracting a group of 24 is given by (80 * 24) - 24. To explain this step-by-step:

  1. We start by multiplying 80 by 24, which gives us the first part of our expression, 80 * 24.
  2. After obtaining the result of that multiplication, we subtract one group of 24 from it, which translates mathematically to '- 24'.

The correct formula or expression that represents this calculation is therefore Option A: (80 * 24) - 24. This approach is analogous to unit conversion where we multiply the given units with the conversion factor to obtain a new unit and then adjust accordingly. It also relates to the systematic approach of solving math problems - for example, calculating the number of combinations or interpreting exponents when performing operations in scientific notation as presented in various examples.
