I do not know

To find out how much Juan spent on the two tires, we need to divide the total cost of his bike ($65) by the number of tires he bought (2).

To calculate this:
1. Divide the total cost of the bike by the number of tires: $65 / 2 = $32.50.

Therefore, Juan spent $32.50 on the two tires for his bike.
