To find the cost of each of the first three tires, we can set up an equation based on the given information.
Let the cost of each of the first three tires be \( x \). According to the holiday deal, the total cost for three tires at price \( x \) plus the fourth tire for $5 is given as:
\[ 3x + 5 = 237.50 \]
Now, we can solve for \( x \):
- Subtract $5 from both sides:
\[ 3x = 237.50 - 5 \] \[ 3x = 232.50 \]
- Divide both sides by 3:
\[ x = \frac{232.50}{3} \] \[ x = 77.50 \]
Thus, the cost of each of the first three tires is $77.50.
Therefore, the correct response is $77.50.
