Answer: 5 seed packets
Explanation: we can find the number of flowers each packet grows by dividing the number of flowers by the number of packets.
16/2=8 so we know that each packet grows 8 flowers.
To find out how many packets we need to grow 40 flowers we can divide 40 by 8 to see how many times a packet of flowers is needed.
40/8=5 so we know we need 5 packets to grown 40 flowers.
