Sutopa has 3/4 of the money Maneet has. Maneet has $18 less than Kim. Together, they have $286.40. How much money does each of t

anastassius [24]

Solving a system of equations we can see:

Sutopa has $73.20
Maneet has $97.60
Kim has $115.60

<h3>How much money each of them has?</h3>

First, let's define the variables:

S = money that Sutopa has.
M = money that Maneet has.
K = money that Kim has.

We can write the system of equations:

S = (3/4)*M

M = K - $18

S + M + K = $286.40

First, we can rewrite the second equation to get:

K = M + $18

Now we can replace the first and second equations into the third one:

(3/4)*M + M + (M + $18) = $286.40

Now we can solve this for M:

M*(1 + 1 + 3/4) = $286.40 - $18

M = $268.40*(4/11) = $97.60

Now we can find the other two values:

K = M + $18 = $97.60 + $18 = $115.60

S = (3/4)*M = (3/4)*$97.60 = $73.20

Are you looking for the percentage? If you are, then you just have to find 8/9, which is about 0.89, or 89%.

<u>Answer:</u>

Below!

<u>Step-by-step explanation:</u>

<u>The best way to answer this question is to read the statement carefully.</u>

=> Five less than twice a number = 2x - 5
=> Five times the sum of two numbers = 5(x + y)
=> The difference of 5 and a number, squared = (5 - x)²

Hoped this helped.
