Answer: She will earn $53.82 for selling all the containers
Explanation:
Total amount of berries that Stella has is 6.3 kilograms. If She packs 0.35 kilograms of berries into each container, it means that the number of containers containing 0.35 kilograms of berry each would be
6.3/0.35 = 18 containers.
She then sells each container for $2.99. If she sells all the containers, it means that the total amount the she will earn will be
18 × 2.99 = $53.82
