Mr and Mrs Cheng went on an excursion with their 6 children. An average amount of $84 was spent by each adult while an average amount of $62 was spent on
each child. What was the average amount of money spent on each person?
avg = totalcost/totalpeople
= (2*84 + 6*62)/(2+6)
Thank you so much Steve!! :)
To find the average amount of money spent on each person, we need to calculate the total amount spent and divide it by the total number of people.
Let's start by calculating the total amount spent on adults. We know that Mr. and Mrs. Cheng went on the excursion, so there are two adults in total. The average amount spent on each adult is $84, so the total amount spent on adults is 2 * $84 = $168.
Next, let's calculate the total amount spent on children. There are 6 children in total, and the average amount spent on each child is $62. So, the total amount spent on children is 6 * $62 = $372.
To find the total amount spent on all people, we add the amount spent on adults and the amount spent on children: $168 + $372 = $540.
Finally, we divide the total amount spent by the total number of people, which is 2 adults + 6 children = 8 people. Thus, the average amount of money spent on each person is $540 / 8 = $67.50.
Therefore, the average amount of money spent on each person is $67.50.
