Question 1 • Mathematics III

A cell phone carrier offers two plans for text messaging. Plan cap A costs 20 dollars per month plus 0 point 0 5 dollars per text. Plan cap b costs 10 dollars per month plus 0 point 1 0 dollars per text. For how many text messages per month are the plans the same cost?

Answer
A
30
B
300
C
200
D
20

Explanation

Let x be the number of texts. Set the plans’ costs equal: 20 + 0.05x = 10 + 0.10x. Subtract 10 and 0.05x from both sides to get 10 = 0.05x, so x = 200. The plans cost the same at 200 texts per month, choice A.
