Question

Janelle's parents got a special offer of $75 per person for each train trip. If there are 4 people in Janelle's family, what is the total cost of each train trip?

Answer 1

Answer:

Cost per person = $75

Cost for 4 persons in Janelle's family = 4 x $75 = $300

Therefore, the total cost of each train trip = $300

Explanation:

From the above working, we will discover that the cost for each person's train trip is $75. Therefore, if 4 people in the family will be making the same train trip at the same cost, the total number of people will be multiplied by the cost per person.

Alternatively, it can be obtained by adding $75 in four places. i.e:

$75+$75+$75+$75 = $300.

This gives us the total cost of the train trip.
