Answer: 55 + 12d.
Explanation:
To simplify the expression, let's break it down step by step.
1. The cost for each person's lunch is $3 for the sandwich, $3 for the French fries, and two drinks (2d).
- So, the cost for each person's lunch is 3 + 3 + 2d.
2. There are 6 people in the group.
- Multiply the cost of each person's lunch by 6: 6(3 + 3 + 2d).
3. Amanda also buys a cake for $12 and a salad for $7, which everyone will share.
- Add the cost of the cake and salad: 12 + 7.
Putting it all together, the simplified expression for the total cost is:
6(3 + 3 + 2d) + 12 + 7
Now you can simplify further by multiplying 6 with each term inside the parentheses:
6 * 3 + 6 * 3 + 6 * 2d + 12 + 7
This simplifies to:
18 + 18 + 12d + 12 + 7
Combining like terms:
18 + 18 + 12 + 12d + 7
Now, add the numbers:
18 + 18 + 12 + 7 = 55
So, the simplified expression representing the total cost is 55 + 12d.
