is 90 mg of adderall (dextroamphetamine and racemic amphetamine) a fatal amount for a 215 lbs adult male with a medium-high tolerance? (not taking this amount, was just asked this question)

Depends on person.: According to FDA "Individual patient response to amphetamines varies widely. While toxic symptoms occasionally occur as an idiosyncrasy at doses as low as 2 mg, they are rare with doses of less than 15 mg; 30 mg can produce severe reactions, yet doses of 400 to 500 mg are not necessarily fatal." Safest thing to do is follow your doctor's prescription for you, and don't experiment.
