STEP 1

Assumptions
1. There are $\mathrm{p}$ pens in one box.
2. Denise has 4 more pens than what is contained in 2 boxes.

STEP 2

First, we need to express the number of pens in 2 boxes. Since there are $\mathrm{p}$ pens in one box, there will be $2\mathrm{p}$ pens in two boxes.
$$\text{Pens in 2 boxes} = 2 \times \text{Number of pens in one box}$$

STEP 3

Now, we write the expression for the number of pens in 2 boxes using the given value $\mathrm{p}$.
$$\text{Pens in 2 boxes} = 2\mathrm{p}$$

STEP 4

Next, we need to express how many pens Denise has. According to the problem, Denise has 4 more pens than what is in 2 boxes.
$$\text{Denise's pens} = \text{Pens in 2 boxes} + 4$$

STEP 5

Now, we substitute the expression for the number of pens in 2 boxes into the expression for Denise's pens.
$$\text{Denise's pens} = 2\mathrm{p} + 4$$

The algebraic expression for how many pens Denise has is therefore:
$$\text{Denise's pens} = 2\mathrm{p} + 4$$ This is the final expression representing the number of pens Denise has.
