Answer:
answer B is correct of this question
Answer:
Step-by-step explanation:
A = [(3x2)/2] + [(4x2)/2] - 1/2
A = 3 + 4 - 1/2
A = 6.5
We have the following:
The formula to calculate the cost is as follows:

In this case, p is equal a 1700, replacing:

Therefore, the cost of 1700 magnets is $1200
Time = distance / speed
time = 3636 / 520 = 6.99 hrs rounds to 7 hrs
