(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Suppose it is the season for harvesting apples. You can earn (-1/3)

t^3 + 6t^2 + 16t + 10 GBP per kilo for the

apples you sell in good condition, where t denotes the number of days from the beginning of the harvest.

However you will lose apples to rot at the rate of 4t - 6 kg/day. On what day after harvest begins should

you sell your apples to maximise your revenue?

3. The attempt at a solution

It might just be because my head isn't working particularly well at the moment, but I can't see exactly what I need to differentiate and how the rate of change of value of apples relates to the rate of change of volume of apples.

Help appreciated :)
