Answer:
40 miles a day
Step-by-step explanation:
The difference in fixed charge is $20; the difference in mileage charge is $0.50 per mile. So it will take $20/$0.50 = 40 miles for the extra mileage cost to eat up the savings in fixed cost. At that mileage, both companies will charge the same amount:
A: 90 + 0.30·40 = 102
B: 70 + 0.80·40 = 102
39 times 3 and 15 times 3 then 27 times 2 then add together to get 216
-5 could not be used in the table again, because we have the value of x=-5 for the value of 15. Therefore correct option is C.
Answer: C. -5
