    A) 2277 = 110% of number in 2013

    b) Number in 2013 = 90% of year before, 2012

    2277 = 110% of Number in 2103

    2277 = (110/100) * Number in 2013

    2277 * 100/110 = Number in 2013

    2070 = Number in 2013

    Number in 2013 is = 2070

    b) Number in 2013 = 90% of year before, 2012

    2070 = (90/100) * Number in 2012

    2070 * 100/90 = Number in 2012

    2300 = Number in 2012

    Hence number in 2012 = 2300 student athletes.
