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
<h3>The answer is:</h3><h2>D. 5 hours</h2><h2 />
The equation should be:
(70x) - (20x) = 250
Because we have all the possible answers, we can plug one of them into x to see if it equals 250 miles.
Use an educated guess. I'm going to go with 5 because it seems reasonable.
(70 * 5) - (20 * 5) = 250
Let's check to see if it equals 250:
Therefore, the answer is D. 5 hours.
