A

4 pens for $4.44

B

5 pens for $6.05

C

6 pens for $6.42

D

7 pens for $7.82

Answer 1

To find the price per pen for 11 ballpoint pens costing $11.77, we can calculate:

\[
\text{Price per pen} = \frac{\text{Total price}}{\text{Number of pens}} = \frac{11.77}{11} \approx 1.070
\]

Now, let's check the price per pen for each option.

**Option A:** 4 pens for $4.44
\[
\text{Price per pen} = \frac{4.44}{4} = 1.11
\]

**Option B:** 5 pens for $6.05
\[
\text{Price per pen} = \frac{6.05}{5} = 1.21
\]

**Option C:** 6 pens for $6.42
\[
\text{Price per pen} = \frac{6.42}{6} = 1.07
\]

**Option D:** 7 pens for $7.82
\[
\text{Price per pen} = \frac{7.82}{7} \approx 1.1186
\]

From these calculations, the only option where the price per pen is approximately the same as $1.070 is:

**Option C**: 6 pens for $6.42.

Thus, the answer is **C**.
