Answer:
There are 10 packets of sweet-pepper seeds and 6 packets of hot-pepper seeds.
Explanation:
Let h represent the number of packets of hot pepper seeds. Then 16-h is the number of packets of sweet pepper seeds. The total cost of a 16-packet mix is ...
4.56h + 2.32(16 -h) = 3.16·16
2.24h + 37.12 = 50.56 . . . . . . . simplify
2.24h = 13.44 . . . . . . . . . . . . . . subtract 37.12
13.44/2.24 = h = 6 . . . . . . . . . . divide by 2.24
16 -h = 16 -6 = 10 . . . . . . . . . . . number of sweet pepper seed packets
