One air fryer for sale uses 239 Joules of energy to cook a meal and has an efficiency of 80%. How much energy will be used to cook this meal? (1 point)
To find out how much energy will be used to cook the meal, we need to multiply the energy used (239 Joules) by the efficiency (80%).
Energy used = 239 Joules * 0.80 = 191.2 Joules
Therefore, 191.2 Joules of energy will be used to cook this meal.
To calculate the amount of energy that will be used to cook the meal, we need to multiply the energy consumption of the air fryer by its efficiency.
Step 1: Convert the efficiency to a decimal.
The efficiency of 80% can be written as 0.80.
Step 2: Multiply the energy consumption by the efficiency.
239 Joules × 0.80 = 191.2 Joules
Therefore, the energy used to cook the meal is approximately 191.2 Joules.
