A batch of 1 000 kg of mangoes is stored in a controlled‑atmosphere room for 4 weeks. The weekly weight loss due to respiration is L_r = 0.02 T % where T is the storage temperature in °C (valid for 10 °C ≤ T ≤ 20 °C). In addition, fungal decay causes an extra weekly loss of L_f = 0.5 (T - 12) % for temperatures above 12 °C and zero otherwise. What is the highest whole‑degree temperature (in °C) that can be used so that the total weight loss after 4 weeks does not exceed 8 %?
