Answer 1

Let's assume the cost of each of the first three tires is x.

According to the deal, Lydia pays $10 for the fourth tire.

So, the total cost of the four tires is x + x + x + $10 = $266.50.

Simplifying the equation, we get 3x + $10 = $266.50.

Subtracting $10 from both sides, we get 3x = $256.50.

Dividing both sides by 3, we get x = $85.50.

Therefore, the cost of each of the first three tires is $85.50.
