What are the differences? It's coming up in math tomorrow and I completely forgot.
One calculates with the approach g(-x). So: g(-x) = -3/-x = 3/x. But the result is not -g(x), but g(x)
100% = 93 kg
75% = 93 / 100 * 75

70% = 69.75 / 100 * 70
70% = 48,825 kg
Recycling paper = 48,825 kg

This is a math task where I need help.
