Miamor wanted to make note cards by cutting pieces of paper in half. Before starting she got seven more pieces to use. When she was done she
had 28 half pieces of paper. With how many full pieces did she start?

14 pieces

Step-by-step explanation:

Let the number of pieces of paper she had at first be x.

Before starting she got seven more pieces to use. This can be written as:

= x + 7

When she was done she had 28 half pieces of paper. This can then be written as:

x + 7 = (28 × 1/2)

x + 7 = 14

x = 14 - 7

x = 7

Since x = 7, she started with:

= x + 7

= 7 + 7

= 14 pieces
