Question

All carry-on bags for a certain airline can have a maximum weight of
25
pounds. Each person is only allowed
1
carry-on bag.

The airline allows pets to be brought on board in a pet carrier, but the total weight of the pet and pet carrier must be at most
20
pounds.

A family with
5
bags finds out that some of their bags are too heavy. They decide to move things around between the bags. Afterwards, the weight of each bag is the same and is exactly the maximum weight allowed.



Which equation and solution represent the total weight,
t
, in pounds, of all
5
bags?



A.
t
5
=
25

t
=
5

B.
t
5
=
25

t
=
125

C.
5
t
=
25

t
=
5

D.
5
t
=
25

t
=
125

Answer 1

Each bag weighs 25 lb and there are 5 bags, so the total t satisfies t/5 = 25. Solving gives t = 25·5 = 125.

Answer: B.
