Final answer:

The equation that expresses the total cost of renting skates in terms of the number of children (C) is: Total Cost = Cost per adult x number of adults + Cost per child x number of children. Given that the cost per adult is $4 and the total cost is $16, the equation can be simplified to Total Cost = $4 + $2.4 x number of children.

Step-by-step explanation:

The equation that expresses the total cost of renting skates in terms of the number of children (C) is:

Total Cost = Cost per adult x number of adults + Cost per child x number of children

Given that the cost per adult is $4 and the total cost is $16, we can write:
Total Cost = $4 x 1 + Cost per child x 5

Simplifying the equation, we get:
16 = 4 + 5Cost per child

Subtracting 4 from both sides, we have:
12 = 5Cost per child

Dividing both sides by 5, we find:
2.4 = Cost per child

Therefore, the equation is:
Total Cost = $4 + $2.4 x number of children
