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.

Three friends have bags that each weigh the same amount. The total weight of their bags is exactly the maximum weight allowed for
1
bag.



Which equation can be used to determine the weight,
x
, in pounds, of each bag?



A.
3
x
=
25

B.
x
=
3
(
25
)

C.
x
+
3
=
25

D.
x
=
25
+
3

Answer 1

Three bags at x pounds each have total weight 3x, and that total equals the one-bag maximum 25. So 3x = 25, choice A. (Hence x = 25/3 pounds.)
