Answer: B. Add 7 and 6, then divide by 18, and then multiply the result by 100.
Step-by-step explanation:
Given : At the grocery store, Rashida purchased 2 oranges, 7 bananas, 3 apples, and 6 pears.
Total fruits = 2+7+3+6=18

[i.e. divide by 18, and then multiply the result by 100]
Hence, the correct description of steps : B. Add 7 and 6, then divide by 18, and then multiply the result by 100.
