Final answer:
The best estimate for the amount of money Trini will pay for the towing company to tow her car is between $140 and $150.
Step-by-step explanation:
To find the best estimate for the amount of money Trini will pay for the towing company to tow her car, we need to calculate the total cost. The towing company charges a fee of $80 plus $3 per mile. Since Trini is 20 to 30 miles from the nearest car repair shop, we can use an average of 25 miles. So, the total cost would be $80 + ($3 x 25) = $155.
Therefore, option b. 140 > M > 150 is the best estimate for the amount of money Trini will pay for the company to tow her car.
