Answer:

  • ≈ 19.5 days

Step-by-step explanation:

  • Initial Value b = 8
  • Rate of Change  m = 15

Equation of the line:

  • y = 15x + 8

Find x when y = 300:

  • 15x + 8 = 300
  • 15x = 300 - 8
  • 15x = 292
  • x = 292/15
  • x ≈ 19.5 days
  • b=initial value=8
  • m=rate if change(Slope)=15

[tex]\\ \sf\longmapsto 300-8=15x[/tex]

[tex]\\ \sf\longmapsto 292=15x[/tex]

[tex]\\ \sf\longmapsto x=\dfrac{292}{15}[/tex]
