Answer

Explanation:

Step1: Check rating

Compass C has 4.8 stars, Compass A has 4.5 stars, Compass D has 4.4 stars, and Compass B has 3.5 stars. We discard Compass B as it has less than 4 - star review.

Step2: Calculate number of compasses and cost combinations

For Compass A: Each pack has 9 compasses. To get 30 compasses, we need at least 4 packs (since $9\times3 = 27<30$ and $9\times4=36$). The cost of 4 packs is $12\times4 = 48$ dollars. For Compass C: Each pack has 1 compass. To get 30 compasses, we need 30 packs. The cost of 30 packs is $1.85\times30=55.5$ dollars which is over - budget. For Compass D: Each pack has 10 compasses. To get 30 compasses, we need 3 packs. The cost of 3 packs is $17.5\times3 = 52.5$ dollars which is over - budget.

Answer:

Compass A
