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.
