Question

In March of 2012, GM reported a 12% increase in number of vehicles sold compared to March of 2011. If the total number of vehicles sold by GM in March of 2012 was 231,000, how many vehicles were sold in March of 2011?

Answer 1

x*.12+x=231000 solve for x

Answer 2

et x = number of vehicles sold in 2011

equation:
x + 0.12x = 231000
solve for x:
1.12x = 231000
x = 206250

there were 206,250 vehicles sold in March of 2011.
