Question

Write a function rule to represent the situation.the total cost C for g grams of bolts if each gram costs $3.29

Answer 1

Let C represent a function in the following way:

C(x) where, x is the grams of bolts.

Then, a function rule that represent the situation will be:

C(x) = 3.29x

For example

If we have 1 gr of bolts then the cost is:

C(1) = 3.29(1) = 3.29

On the other hand, if we have 0 gr of bolts, then the cost is:

C(0) = 3.29(0) = 0

So our equation match. We can conclude that a function that represent the situation will be:

C(x) = 3.29x
