Final answer:
Kendra will plant 4 rows of peppers this year.
Step-by-step explanation:
First, let's find the ratio of rows of tomatoes to rows of peppers that Kendra planted last year:
Ratio of tomato rows to pepper rows = 6/8 = 3/4
Since Kendra wants to keep the same ratio this year, we can set up a proportion:
3/4 = 3/unknown
Cross-multiply to solve for the unknown number of rows of peppers:
4 * 3 = 3 * unknown
12 = 3 * unknown
Divide both sides of the equation by 3 to isolate the unknown:
12/3 = unknown
unknown = 4
Therefore, Kendra will plant 4 rows of peppers this year.
