Answer (3)
12c + 3a + 6d= total bill when d stands for dessert and a stands for appitizer and 12 stands for drinks and meals
The correct expression for the given condition will be;
⇒ T = 12x + 3y + 6z
Where, x is cost of drink and meal, y is cost of appetizer , z is cost of **cake **and T is total cost.
What is an expression?
**Mathematical **expression is defined as the collection of the numbers variables and functions by using **operations **like addition, subtraction, multiplication, and division.
Given that;
A family of 12 went to the local Italian restaurant for dinner. Every family member **ordered **a drink and meal, 3 ordered an appetizer, and 6 people ordered cake for dessert.
Now,
Let x is cost of **drink **and meal, y is cost of appetizer, z is cost of cake and T is total cost.
So, We can formulate;
⇒ T = 12x + 3y + 6z
Thus, The correct expression for the given condition will be;
⇒ T = 12x + 3y + 6z
Where, x is cost of drink and meal, y is cost of appetizer , z is cost of **cake **and T is total cost.
