Explanation:
To find the total cost of buying 2, 3, or 4 gallons of juice, we can use the given rule:
c = 3.25g
Plugging in g = 2, 3, or 4, we get:
c(2) = 3.25(2) = 6.50
c(3) = 3.25(3) = 9.75
c(4) = 3.25(4) = 13.00
So the total cost of buying 2 gallons of fruit punch is $6.50, the total cost of buying 3 gallons is $9.75, and the total cost of buying 4 gallons is $13.00.
The table can be filled as follows:
| Gallons of juice (g) | Total cost (c) |
|---------------------|----------------|
| 2 | $6.50 |
| 3 | $9.75 |
| 4 | $13.00 |
