{2x - 6y = 12

{-2x + 6y = -14

{2x - 6y = 12                    (+)

Patricia, Luca and Dauda shared an amount of money such that, Patricia had twice as much
inn [45]

Answer:

GH 1533

Step-by-step explanation:

Let Dauda's share of the money=x

Patricia had twice as much  as Dauda, therefore:

Patricia's share=2x

Luca had GH 600.00 more than Dauda, therefore:

Luca's Share =x+600

If Patricia had GH 2,000.00

Then: 2x=2000

x=1000

Therefore:

  • Dauda's Share=GH 1000
  • Patricia's share=GH 2000
  • Luca's Share =1000+600=GH 1,600

Next, we determine the average share.

\text{Average Share=}\dfrac{1000+2000+1600}{3}\\=\dfrac{4600}{3}\\\\=$GH 1533.33\\\text{Average Share} \approx $GH 1533 (to the nearest GH)
