Thank you for the opportunity to help you with your question!

Let last year be x

this year will be x - 3

games won last year = 80% of x  = 0.8

anticipated this year win = 90% of total games this year which = (x - 3)x 0.9

Games playing this year  =

First find the value of x

0.8x = 0.9(x-3)

X = 30

hence games this year = 30 - 3 = 27

Answer = 27 games played this year.

Please let me know if you need any clarification. I'm always happy to answer your questions.
