Answer:
B.25$
Step-by-step explanation:
to make the money less one of the freinds will carry 9kg and the other 12 kg the last one carries the left luggage weighing 7kg and 6kg which add up to 13kg.
the first freind won't pay anything as he is passing 9kg luggage
the second will pay : 12-10 =2 so 2kg*5$=10$
the last freind will pay 13-10=3 so 3kg*5$=15$
to find the total money the pay we will add 10$ and 15$ which became 25$.
hope this helped.
The answer to your question is 35,568
We can find the price per arc by dividing the total price by the amount of arc.
so in this case
5625 is the total money spent
and 4.5 is what they get when spending that amount of money
5625 / 4.5
= 1250
The price per arc is $1250
therefore, the answer is $1250.
