b.

Betty was making a new flag. She wanted the stripes to alternate colors. She needed a total of 13 stripes and wanted 1 more red stripe than she has white stripes.

Answer 1

w+w+1=13 or 2w = 12

Explanation:

Total no. of strips = 13

Let there are w white stripes.

Red strips = w+1

ATQ,

Red strips +white strips = 13

w+w+1=13

2w+1=13

2w = 13-1

2w = 12

Hence, this is the required equation.
