Sasha grew 36 plants with 9 seed packets. How many total seed packets does Sasha
need if she wants to have 76 plants in her backyard in all? Solve using unit rates.
seed packets
36/9=4 so there are 4 seeds in each packet. If she already has 36 plants, she only need 40 more to get the 76 she wants. 40/4=10 so she needs 10 more seed packets.
