Question

Each box of envelopes contains 12 envelopes. Mr. Jensen buys an unknown number of boxes. Which expression shows the total number of envelopes Mr. Jensen buys, using x for the number of boxes?

A) x + 12
B) x - 12
C) 12x
D) 12 + x

Answer 1

The expression that shows the total number of envelopes Mr. Jensen buys, using x for the number of boxes, is 12x (Option C).

Step-by-step explanation:

The expression that shows the total number of envelopes Mr. Jensen buys, using x for the number of boxes, is 12x (Option C).

Since each box contains 12 envelopes, we can multiply the number of boxes, x, by 12 to find the total number of envelopes. This is represented by the expression 12x.

For example, if Mr. Jensen buys 3 boxes, the total number of envelopes he buys would be 12 x 3 = 36 envelopes.
