Idon't understand this could someone explain this?

$5032 is how much room and board costs and it is $6 per meal.

Explanation:

To find the cost per meal, we can first subtract $5110 from $5146 to get $36.

Then we do 19-13 to get 6. This is the difference between the two plans.

After that, divide 36 by 6 to get $6, which is the price per meal.

To get the cost of just room and board, we can take one of the plans (I will use the 13 meal one), then do 6×13=$78. This means that you paid a total of $78 in meals.

Then do $5110-$78 and you get $5032, the amount for room and board.

Hope this helps :)
