A state government needs a new accounting system. The buyer of the new system is analyzing two different applications. The first application has a retail price of $24,050. In addition, the government receives a special beta test discount of 15% and then a 10% discount for being a repeat customer. The retail price does not include a $2,500 delivery charge and an installation charge of $750. The second application has a retail price of $25,500, but the government only gets one discount of 20%. In addition, they must pay a $2,000 delivery charge and a $1,000 installation fee. If the state chooses to purchase the beta system that is cheaper, about what percent would they save.
