Answer:
Constant of variation is 24.
Step-by-step explanation:
Inverse variation states that a relationship between two variables in which the product is remain constant.
If one variable increases then, the other one decreases in proportion so that the product is unchanged,
if y is inversely proportional to x i.e or
;where k is the constant of variation.
It is given that 3 identical water pumps takes 8 hours to fill a pool,
since, it will take less time with more pumps, so it is an inverse variation.
By definition of inverse variation;
Substitute the values to solve for k;
Multiply by 3 to both sides we get;
Simplify:
k = 24
Therefore, the constant of variation is, 24
Answer: He makes $111.80 in 2 days.
Step-by-step explanation:
Since we have given that
Amount he makes in 3 days = $167.70
Number of days = 3
We need to find the amount he makes in 2 days.
We will use "Unitary method" to find the amount s in 2 days.
In 3 days , amount = $167.70
In 1 day, amount is given by
In 2 days, amount is given by
Hence, he makes $111.80 in 2 days.
