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
Well first you need to divide 4 by 12 which is 3. So 15/3=5 so she jarred in 5 days.
Solve by dividing 16 divided by 24
The answer is 2/3
L*b becomes (1.2)*(1.3)*l*b=1.56 l*b
so, 56% increase
