Answer 1

The total cost of meals for a number of adults and children with given meal costs can be found using the expression: (a * AED 21.5) + (c * AED 11.5), where 'a' is the number of adults and 'c' is the number of children.

Step-by-step explanation:

The student is asking for an expression to represent the total cost of meals for adults and children, where the cost per adult portion is AED 21.5 and the cost per child portion is AED 11.5.

If there are a adults and c children, the total cost can be calculated using the following expression:

Total Cost = (Number of Adults × Cost per Adult) + (Number of Children × Cost per Child)

Mathematically, this can be written as:

Total Cost = (a × AED 21.5) + (c × AED 11.5)
