Final answer:
To represent the total cost Briana spends on candy at Sugary, we need to consider the cost of the gummy frogs and the Pop Rocks separately. The linear function, f(x), to represent the total cost Briana spends on candy at Sugary is f(x) = 4.49x + 1.29.
Step-by-step explanation:
To write a linear function to represent the total cost Briana spends on candy at Sugary, we need to consider the cost of the gummy frogs and the Pop Rocks separately.
Let's define x as the weight of gummy frogs in pounds that Briana buys. The cost of gummy frogs would be 4.49x dollars. The cost of the Pop Rocks, which is a fixed price, would be 1.29 dollars.
Therefore, the linear function, f(x), to represent the total cost Briana spends on candy at Sugary would be:
f(x) = 4.49x + 1.29
