Appealing college to match financial aid offer

BC Breakdown:

Tuition: $50,480
Fees: $1,346
Room and Board: $13,818
Books and Misc: $2,650
Total: $68,294
Note: BC estimates on my financial aid award page that the cost of attendance is $71,379
Federal Work study: “During the semester break and spring break, you may work up to 29 hours per week”. I assume I could get another job during the summer too.

Lehigh Breakdown:

Activity Fee: $200.00
Books and Supplies: $1,000.00
Lab Fee: $550.00
Miscellaneous: $1,065.00
Room and Board: $13,120.00
Technology Fee: $420.00
Tuition: $50,320.00
Total: $66,675.00

Maybe I was wrong and they’re actually a lot closer in cost? I don’t know why BC gives it’s total as $3,000 more than in the breakdown. Is that the padding you’re talking about?
