danjs · Answer

Total Cost = Initial 300 min cost + (# min over 300)*(cost per minute over 300)

Wants to spend at most $50

$$50 \ge 29.95 + (0.19)*(minutes~ more)$$

danjs · Answer

those are the numbers put in, you can solve for the additional min,  and add that to 300.  That is the most she can purchase for 50 dollars
