Emily is shopping for clothes at a store where all items have a 25% discount. There is also a special deal that states 'Buy 3 and get 50% off', which means the discount increases to 50% on each item if she buys three. If Emily has already bought two items priced at $50 and $30, what is the maximum price she can pay for the third item while keeping her total expenditure the same as what she spent on the first two items?
