Final answer:
To find the number of possibilities for lunch that Paul can have, we need to subtract 2 from the total number of sandwiches he has. Paul has 5 sandwiches, so when he doesn't want 2 of them, he is left with 3 sandwiches.
Step-by-step explanation:
To find the number of possibilities for lunch that Paul can have, we need to subtract 2 from the total number of sandwiches he has. Paul has 5 sandwiches, so when he doesn't want 2 of them, he is left with 5 - 2 = 3 sandwiches. For each sandwich, he has 7 sides and 10 drinks to choose from. To find the total number of possibilities, we multiply the number of choices for each category: 3 (sandwiches) x 7 (sides) x 10 (drinks) = 210 possibilities for lunch.
