Answer:
2500 pence (C = 2500)
Step-by-step explanation:

From the given information, t is the number of texts so essentially you will plug in the number of texts provided (150) in the place of the variable t.

Apply the same thing to minutes, plug in the number of minutes (50) in the place of the variable m.

Now multiply the substitutes with the co-efficient.
(10*150=1500 & 20*50=1000)
Add the addends
C = 2500
