To find the cost of each of the first three tires, let's denote the price of each tire as \( x \). According to the holiday deal, Sebastian bought three tires at the price \( x \) each and the fourth tire at $5.
The total cost equation can be set up as follows:
\[ 3x + 5 = 237.50 \]
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. The answer is:
$77.50
