Tiana needs 49 seed packets to have a total of 882 plants in her backyard.
18 plants come from each seed packet.
28 seed packets grew 504 plants.
Because 28 Multiplied by 18 = 504.
Then I made a few estimates and got 864 with 48 packets then tried 49 packets and got 882.
Hope this helped!

Identifying the Constant of Proportionality. ... The constant of proportionality is the ratio between two directly proportional quantities. In our tomato example, that ratio is $3.00/2, which equals $1.50. Two quantities are directly proportional when they increase and decrease at the same rate.
