Question

Emir sells hot dogs during baseball games. The function f(x) tells you the amount of money
Emir collects from selling x hot dogs.
What does f(31) = 62 tell you?
When Emir sells 31 hot dogs, he collects $62.
When Emir sells hot dogs for 31 minutes, he collects $62.

Answer 1

The first statement is correct.

Since f(x) gives the money collected from selling x hot dogs, f(31)=62 means when Emir sells 31 hot dogs he collects $62. The second (31 minutes) is incorrect because x counts hot dogs, not minutes.
