Let the cost of one guitar pick be \( p \) dollars. Then the cost of one guitar string would be \( p + 1 \) dollars.
You bought 25 guitar picks and 25 guitar strings. The total cost can be expressed as:
\[ 25p + 25(p + 1) = 50 \]
Now, simplifying the equation:
\[ 25p + 25p + 25 = 50 \]
Combine the terms:
\[ 50p + 25 = 50 \]
Now, subtract 25 from both sides:
\[ 50p = 25 \]
Dividing both sides by 50 gives:
\[ p = \frac{25}{50} = \frac{1}{2} \]
So, the cost of one guitar pick is \( \frac{1}{2} \) dollar or 50 cents.
Now, to find the cost of one guitar string:
\[ p + 1 = \frac{1}{2} + 1 = \frac{1}{2} + \frac{2}{2} = \frac{3}{2} \]
The cost of one guitar string is therefore:
\[ \frac{3}{2} \text{ dollars} = 1.50 \text{ dollars} \]
Thus, the cost of one guitar string is $1.50.
