Answer:
Mr. Lim will have $2500
Step-by-step explanation:
Given:
The total amount of money which Mr. Lim, Mr. Tan and Mr. Chan is $8650;
Mr. Lim has $450 more than what Mr. Tan has;
Mr. Chan has double the amount of money than what Mr. Tan has.
Therefore, if we assume that the amount of money Mr. Tan has as x, then...
Total money = Mr. Tan + Mr. Lim + Mr. Chan
therefore,
8650 = x + (x + 450) + 2x
8650 = <u>x + 2x + x</u> + 450
8650 = 4x <u>+ 450</u>
8650 - 450 = 4x
8200 = <u>4</u>x
8200/4 = x
2050 = x
As we assumed earlier, x will be equal to the amount of money Mr. Tan has and the question is asking us how much money Mr. Lim has. To find this out, you have to add $450 to the amount of money Mr. Tan has which is $2050. This is because the question also gives us that Mr. Lim has $450 more that Mr. Tan.
I hope this helped you :)
Answer: 31
Step-by-step explanation:
The two disks that we know Gina has are: 2 and 8.
We want to find tha largest sum that Gina's disks can have:
This means that the other 3 disks must be the largest possible ones.
We know that Monique has the disks 7 and 9.
The already taken values are: 2, 7, 8, and 9.
The largest values remaining are:
10, 6 and 5.
Then the largest sum that Gyna's disks can have is given by the scenario where Gina draws these 3 disks, and the sum will be:
2 + 8 + 10 + 6 + 5 = 31
I believe you want to know how much each of them SAVED.
Let the amount saved by Michelle be x, the amount saved by Sam be y and the amount saved by Dean be z.
From the givens:
x = 3y (Michelle saves 3 times as much as Sam).......eq1
y = 2+z (Sam saves 2$ more than Dean)
z=y-2.........eq 2
x+y+z = 240 (total amount)......eq 3
substitute by equation 1 in 3:
3y+y+z=240
4y+z=240......eq 4
substitute by 2 in 4:
4y+y-2=240
5y=242
y= 48.4$
from 1:
x=3y
x=145.2$
from 2:
z=y-2
z=46.4$
