what is the cost of 50 beans if 5 beans is $4 and 20 beans is $16

Answer 1

First, find the cost of 1 bean:
1 bean = $4 / 5 = $0.80

Next, find the cost of 20 beans:
20 beans = 20 * $0.80 = $16

Finally, find the cost of 50 beans:
50 beans = 50 * $0.80 = $40

Therefore, the cost of 50 beans is $40.
