Ok I may be young but combine the two reactions to create a compund

Answer:
Explanation:
Since it first order, we use order rate equation
In (
) = -kt where A1 is the final quality = 0.8 (80%), A0 is the initial quality = 1 ( 100%)
also, t half life =
where k is rate constant
k =
= 0.0154
In (
) = - 0.0154 t
-0.223 / -0.0154 = t
t = 14.49 approx 14.5 days from the date the yogurt was packaged
