Respuesta :

Answer = 688 thousand / 688,000

Explanation - 536-517 = 19 so 19000 x 8 + 536000 = 688,000

Thinking it as a propotional increase, find the unit rate of change.

values: (0, 536,000), (-5, 441,000), (-1, 517,000)

unit rate of change:

[tex]\sf \dfrac{y2-y1}{x2-x1}[/tex]

[tex]\dashrightarrow \sf \dfrac{536,000-441,000}{0-(-5)}[/tex]

[tex]\dashrightarrow \sf 19000[/tex]

Therefore, the sales increase by $19000 each year.

After 8 years the sale increasement:

  • $19000 * 8
  • $152000

Total sales amount:

  • current sales + increasement in sales
  • $536,000 + $152000
  • $688,000

So, correct answer is : $688,000
