Final answer:
To find the total time needed to taste test all the variations of the taco franchise's ingredients, we need to calculate the total number of taco variations and multiply it by the time required per taste tester. Then we convert the total time from minutes to hours.
Step-by-step explanation:
In this question, we need to find the total amount of time needed to taste test all the variations of the taco franchise's ingredients. First, we need to find the total number of taco variations by multiplying the number of options for each ingredient together. There are 3 types of taco shells, 5 types of main fillings, 8 types of sauce, and 2 types of lettuce. So the total number of taco variations is 3 x 5 x 8 x 2 = 240.
Since each taste tester requires 5 minutes to eat one taco, we can find the total time needed to test all the variations by multiplying the number of taco variations by 5 minutes. So the total time needed is 240 x 5 = 1200 minutes.
To convert minutes to hours, we divide the total time by 60. Therefore, it will take 1200 minutes / 60 = 20 hours for all the taco types to get taste tested.
