WELL ITS NOT THE FIRST 1 OR THE LAST 1 BECAUSE THEY'RE OUTSIDE THE LIMITS OF THE EQUATION.
THEREFORE IT COULD ONLY BE $60.78 OR $66.60.
ADD UP THE DIGITS AND SEE WHICH ONE IS 18

Chae is right, but there is no equation. (Equations need an = sign.) $57.80 and $76.50 are outside the indicated <I>range</I> of costs. Only one of the two remaining prices will have their digits add up to 18.
I hope this helps a little more.
