Question

The graph shows the calling charges of two cell phone companies. At how many minutes do the two companies charge the same amount?

Α. Ο
B. 15
C. 20
D 4

Answer 1

Answer: The answer would be C

Explanation:

The two lines intersect on (20, 6) so that means that the charging rates were the same when on that point. And since it is asking for how many minutes they charge at the same amount, that would make it 20.

Answer 2

I believe that would be C.
