You can plug in the number to see if it is correct. 4(4) ≤ 16. Sorry, I'm not the best at explaining things.
$72,00?
I'm assuming you are saying $7200, but if you are saying $72, just replace.
6% = 0.06
7200 / 0.06 = 432
So you would get $432. But trust me, no house is that cheap lol

Answer:
Correct option: first one -> 40
Step-by-step explanation:
To solve this problem, we can use a compound rule of three.
The quantity of chocolate and the weight of each chocolate are inversely proportional: to achieve the same earning, if we have more chocolate, we need less grams per chocolate.
Then, the rate of change in quantity multiplied by the rate of change in the grams will be equal to the rate of change in the final earning.
So we have that:
(3/20) * (14/X) = 21/400
42 / 20X = 21 / 400
1 / 10X = 1 / 400
10X = 400
X = 40 grams
Correct option: first one
450 because you are adding +25
