Answer

Explanation:

Step1: Calculate cost for each option to get 30 compasses

For Compass A: $\frac{30}{9}\approx3.33$, need to buy 4 packs. Cost is $4\times12 = 48$ dollars. For Compass B: It has 3.5 - star review, does not meet the criteria, so we don't consider it further. For Compass C: $\frac{30}{1}=30$, cost is $30\times1.85 = 55.5$ dollars which exceeds the budget. For Compass D: $\frac{30}{10}=3$, cost is $3\times17.50 = 52.5$ dollars which exceeds the budget.

Step2: Check if within - budget and meets review criteria

Compass A meets the 4 - star review criteria and the cost of $48$ dollars is within the $50$ - dollar budget.

A. Compass A
