To calculate the energy used to cook the meal, we can use the formula:
Energy used = Energy input x Efficiency
Given that the energy input is 239 Joules and the efficiency is 80% or 0.8, we can plug these values into the formula:
Energy used = 239 Joules x 0.8 = 191.2 Joules
Therefore, the energy used to cook the meal is 191 Joules.
