Which equation represents the following situation?
A large box of cereal contains 5 more ounces than a small box. A large and small box combined
contain 27 ounces of cereal.
A. x + 5x = 27
B. x + (x + 5) = 27
C. x+ 5 = 27

Answer 1

B.

Explanation:

x = small box

(small box + 5 ounces) = large box.

B shows:

x + (x + 5) = 27

Small box + (small box + 5 ounces) = 27 ounces.

Small box + large box = 27 ounces.

————————————————————

Why A and C are incorrect.

A describes:

x + 5x = 27

Small box + 5 multiplied by small box = 27

(5 multiplied by small box is equivalent to 5 small boxes.)

Small box + 5 small boxes = 27

C describes:

x + 5 = 27

small box + 5 ounces = 27

Large box = 27

(We know that a small box + 5 ounces is a large box)
