On a 3-day fishing trip, 4 adults consumed food costing $60. for the same costs per person per day, what would be the cost of food consumed by 7 adults during a 5-day fishing trip?

The total cost is $175.

The first thing that you need to do is calculate the per day cost per person.

$60 was spent on a three day trip. $60/2 = $20 per day. There were 4 adults on the trip, so $20/4 = $5. The cost of food is $5 per person per day.

On a trip with 7 adults the formula to solve the total cost is:

7 adults x 5 days x $5/day = $175.

the answer would be voluntary exchange -

"the act of buyers and sellers freely and willingly engaging in market transactions. moreover, transactions are made in such a way that both the buyer and the seller are better off after the exchange than before it occurred."

hope this : )

i'ts proportional. if the inflation rate is 12% for example, the cpi will be 12% less.

hope it ,
