Question

there were 2,277 student athletes competing in spring sports in 2014. That was 110% of the number from 2013, which was 90% of the number from the year before. How many student athletes signed up for a spring sport in 2012?

Answer 1

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.
