For this case we have a function of the form:
 y = A * (b) ^ x

 Where,
 A: it is the initial amount
 b: is the growth rate
 x: it's time
 Substituting values we have:
 y = 12880 * (1.30) ^ x

 For 20 days we have:
 y = 12880 * (1.30) ^ {20}  y = 2447839
 Answer:
 
the amount will be 2447839 pounds in 20 days

<h2>                             Question 1</h2>

Answer:

The graph is showing the story.

Step-by-step explanation:

Victoria is on the 13th page of the book, she reads 3 pages after every next hour.

After 1st hour she has read = 13 + 3 = 16

As she reads 3 pages after every next hour.

so

After 2nd hour she has read = 16 + 3 = 19

After 3rd hour she has read = 19 + 3 = 22

After 4th hour she has read = 22 + 3 = 25

After 5th hour she has read = 25 + 3 = 28

So the graph is showing this phenomena.

<h2>                          Question 2</h2>

Answer:

The equation that would generate this graph and table would be:

  • y=\:3x+13

Step-by-step explanation:

Given the slope-intercept form of the equation of the line

y=\:mx+b

Taking any two points

(1, 16)

(2, 19)

\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(1,\:16\right),\:\left(x_2,\:y_2\right)=\left(2,\:19\right)

m=\frac{19-16}{2-1}

m=3

Plugging any point, let say (1, 16), and m = 3 in the slope-intercept form to find the value of b (y-intercept).

y=\:mx+b

16=\:3\left(1\right)+b

\mathrm{Switch\:sides}

3\left(1\right)+b=16

\mathrm{Remove\:parentheses}:\quad \left(a\right)=a

3\cdot \:1+b=16

\mathrm{Multiply\:the\:numbers:}\:3\cdot \:1=3

3+b=16

\mathrm{Subtract\:}3\mathrm{\:from\:both\:sides}

3+b-3=16-3

b=13

Thus the equation that would generate this graph and table is:

y=\:mx+b

  • m = 3
  • b = 13

y=\:3x+13

Therefore, the equation that would generate this graph and table would be:

  • y=\:3x+13
