Answer:

x = 3, x = 4

Step-by-step explanation:

To find the zeros of the function, equate f(x) to zero, that is

(x - 3)(2x - 8) = 0

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3 ← smaller solution

2x - 8 = 0 ⇒ 2x = 8 ⇒ x = 4 ← larger solution

BigorU [14]

Based on the calculations, Kirk bought 2.4 bags of popcorn and 7.2 sodas.

Let the number of sodas bought be s.

Let the number of bags of popcorn be p.

<u>Given the following data:</u>

Cost of soda = $4.50.

Cost of popcorn = $1.50.

Total price = $36.
