A company accountant estimates that airfares next year for business trips of a thousand miles or less will increase by 20 percent and airfares for all other business trips will increase by 10 percent. This year total airfares for business trips of a thousand miles or less were $9,900 and airfares for all other business trips were $13,000. According to the accountant's estimate, if the same number of business trips will be made next year as this year, how much will be spent for airfares next year?

Airfares from thousand miles or less business trips will rise by 20% from last year and airfare from business trips for other trips will rise by 10% if the same number of trips as this year are made next year.

Next years airfare spend will be:
1.2*9900 + 1.1*13000
= 11880 + 14300
= 26180
