Question

You are buying bottles of a sports drừnk for a softball team. Each bottle costs$1.19. What function rule models the total cost of a purchase? Evaluate thefunction for 15 bottles

Answer 1

The function rule that models the total cost of a purchase is

f(x) = 1.19x dollars

15 bottles will cost $17.85

Step-by-step explanation

Each bottle costs $1.19.

If one buys x bottles, the total cost of purchase will be

f(x) = 1.19 × x = 1.19x dollars.

Hence, the function rule that models the total cost of a purchase is

f(x) = 1.19x dollars

So, to evaluate the function for 15 bottles.

When x = 15

f(15) = 1.19 × 15 = $17.85

Hope this Helps!!!
