Answer:
- See below
Step-by-step explanation:
This a form of the proportional relationship:
- f(x) = kx, where f(x) - total cost, k- cost of each item, x - number of items
We have:
- f(5) = 12
It means:
- Total cost of 5 cupcakes is $12
In f(x)
- f(x) is total cost
- x is total cupcakes
So in f(5)
- 5 cupcakes cost $12
