Donations to an annual fundraiser are 15% greater than last year. last year, donations were greater 10% than the year before. the amount raised this year is $10,120. how much were raised 2 years ago?

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
