If two pounds of almonds costs $8.20 and 5 pounds cost $19.75, is the cost of almonds proportional to the weight?
1 Answer
No, the cost is not proportional to the weight.
Explanation:
The first time, the cost of each pound of almonds is
8.20/2 = 4.10 .
The next time, the cost of each pound is
19.75/5 = 3.95
Hence the price is not constant.
