the answer is d.

this is because all 4 ordered the same thing, so we multiply all the costs by 4. Then we add 11.50 + 1.50 + 2.75 which equals 15.75, but that’s the cost for only one person, so we multiply it by 4, which is 60

Final answer:

The expression to calculate the cost of the Ross family's dinner before tax and tip is 4(11.5 + 1.5 + 2.75), and the cost of dining out for the Ross family is $63. Hence the correct answer is option D

Step-by-step explanation:

The expression that could be used to calculate the cost of the Ross family's dinner before adding tax and tip is option C: 4(11.5 + 1.5 + 2.75). This expression represents the cost of 4 pasta dishes, 4 drinks, and 4 desserts. To find the total cost, we can calculate it as follows:

  1. Cost of 4 pasta dishes: 4 x 11.5 = 46
  2. Cost of 4 drinks: 4 x 1.5 = 6
  3. Cost of 4 desserts: 4 x 2.75 = 11
  4. Total cost = Cost of pasta dishes + Cost of drinks + Cost of desserts = 46 + 6 + 11 = 63

Therefore, the cost of dining out for the Ross family is $63.

Hence the correct answer is option D
