Answer:
185 minutes.
Step-by-step explanation:
It is possible to model an equation for this, such that
[tex]0.10x + 14.80 = 0.08x + 18.50[/tex]
where x represents the number of minutes.
Then, you solve for x:
[tex]0.10x + 14.80 = 0.08x + 18.50 \\ 0.02x = 3.70 \\ x = \frac{3.70}{ 0.02} \\ x = 185[/tex]
