As finely grained as you can find solutions, the ticket prices MUST be in whole penny quantities, including 0. Children's tickets are priced as BELOW $6.40, and adult tickets are HIGHER than $6.40. Several solutions to the two dimensional problem are possible as long as you take perfect hundredth of a dollar accuracy.
