MHB Find the total sum of money shared by the three girls.

[Johnx1]

Kate, Nora, and Devi shared a sum of money. Kate received 24 dollars and Nora received x dollars more than Kate. Devi received 2x dollars more than kate

a) Find the sum of money shared in terms of x.

my answer: total = 24 + (x+24) + 2(24)b) Nora received $30. Find the total sum of money shared by the three girls.

my answer: 24 + 30 + 48 = 102

Re: How much each recieved

Kate, Nora, and Devi shared a sum of money. Kate received 24 dollars and Nora received x dollars more than Kate. Devi received 2x dollars more than kate

a) Find the sum of money shared in terms of x.

my answer: total = 24 + (x+24) + 2(24)

You've got Kat and Nora right, but Devi would receive 24 + 2x (that's 2x more than Kate). And so the sum \(S\) would be:

$$S=(24)+(24+x)+(24+2x)=72+3x=3(24+x)$$

b) Nora received $30. Find the total sum of money shared by the three girls.

my answer: 24 + 30 + 48 = 102

If Nora received \$30, then to find \(x\), we may write:

$$24+x=30\implies x=6$$

And so:

$$S=3(24+6)=90$$

Does that make sense?

Yes, I miss read the "more" part. Thanks :-)
