Let the price of each of the 3 items be \( x \).
According to the problem, the total amount spent by Samantha can be expressed as:
\[
3x + 6.40 = 19.00
\]
We can solve for \( x \):
1. Subtract $6.40 from both sides:
\[
3x = 19.00 - 6.40
\]
\[
3x = 12.60
\]
2. Now, divide both sides by 3:
\[
x = \frac{12.60}{3} = 4.20
\]
Thus, the individual price of the 3 items is \( x = 4.20 \).
So the answer is \( \text{B. } 4.20 \).
