The table below shows the fees to check bags on a certain airline.

Type of bag Fee per bag

First checked bags 20$
Second checked bags 25$
Exra bags bags 50$

If x represents the total number of bags a person checks and each person checks more than two bags, the equation below can be used to determine C, the total fee for all the bags.

20 + 25 + 50(x - 2) = C

Arianna paid a total of $145 to check all her bags on a flight. How many bags did she check in all?

anonymous · Answer

20 + 25 + 50(x - 2) = 145
distribute:
20 + 25 + 50x - 100 = 145
solve for x:
-55 + 50x = 145
+ 55
50x = 200
/50
x = 4
4 bags were checked.
