<h2>You are technically using PEMDAS, since x equals 6 heres what you do. 2 x (6 + 1) -3</h2><h2>Perenthesies first: 6 + 1 =7 now you mulitiply</h2><h2>2 x 7 = 14 so then subtract 14 - 3= 11</h2><h2 />

To calculate the remaining caffeine, we use the radioactive decay formula which is expressed as An = Aoe^-kt where An is the amount left after t time, Ao is the initial amount and k is a constant we can calculate from the half-life information. We do as follows:
at half-life,
ln 1/2 = -k(6)
k = 0.12/hr
An = 80e^-0.12(14)
An = 15.87 mg
