How much merit aid do you think I'll get?

Have been admitted EA
Major: marketing
UW gpa 3.58
Weighted GPA: 3.85
Upward trend from freshman to junior year (struggled with ADD, is mentioned in letters of rec)
SAT: 1290 superscore 650 E 640 M
Extracurriculars include JV XC and still team, 4 years of concert and marching band ( lead euphonium and section leader junior and senior years), work as a door to door advertiser for a painting company, major leadership position in my church youth group including volunteering as a student leader at a camp for freshman and sophomores, 200 or so hours of community service including 3 mission trips to Mexico to build houses for families, as well as lots of local service work through church.
My LMU essay was particularly excellent, and has been reviewed by professionals. LOR’s should also be great, particularly my counselor letter.
Family income:>$200,000
Live in WA
Have received $21K/year from University of Portland, $17k/year from Trinity University, $16k/year from Chapman and USF, and $13K/year from Gonzaga. LMU is my top choice out of the schools I have gotten into, and will remain at the top unless I get into Santa Clara RD (was deferred EA), or USC (probably not happening lol) so hoping for some decent merit aid.

Also have taken 6 AP (Human geography, APUSH, language and comp., American Government, calculus AB, and Spanish language) and 4 honors classes.

Probably 10-15, at best, since merit is related to your scores relative to the top 25% (1300).
