Question

Mary has a third of the money that Erin has. Erin has $8 less than John. Together they have $267. How much money does each of them have?

Answer 1

Answer:

John has $119 Erin has $111 Mary has $37

Step-by-step explanation:

Consider the provided information.

Let John has x dollar.

Erin has $8 less than John = x-8

Mary has a third of the money that Erin has = 1/3(x-8)

Together they have $267.

$x+x-8+\frac{1}{3}(x-8)=267$

$2x+\frac{1}{3}\times x-\frac{1}{3}\times 8=267+8$

$2x+\frac{x}{3}-\frac{8}{3}=275$

Multiply both sides by 3.

$6x+x-8=825$

$7x=825+8$

$7x=833$

$x=119$

Thus, John has $119

Erin has $8 less than John = $119-$8 = $111

Mary has a third of the money that Erin has = 1/3($119-$8) = $37

Answer 2

Mary = (1/3)x

Erin = x - 8

John = x

Here is your equation:

(1/3)x + (x - 8) + x = 267

Take it from here.
