1. A certain IT department of fewer than 15 people hires coders and system admins. coders are paid 55000 per yr on avg, while sys. admins are paid 45000 per yr on avg. what is the ratio of coders to system admins?
(1) if two coders wer made system admin instead the yearly payroll for IT dept would be 535,000.
(2) if system admins salaries were reduced by one third and coders salaries were increased to 58000. the dept would save 57000 in yearly payroll.
-----------------------------------------------------------------------------------------------------
2.the ratio of SUVs to passenger cars sold at a particular automobile dealer has been declining since 2003 to 2007, while the total sales have remained constant. the total number of vehicles sold in 2007 was divisible by 10. In 2007 were more cars sold that SUVs.
(1)if in 2007 as many SUVs had been sold as cars were sold in 2003, there would have been 36% increase in total vehicle sales.
(2)In 2003 twice as many SUvs were sold as cars.
Please explain how to approach both the problems.
