Answer:
The graph is attached
Step-by-step explanation:
The graph that will represent the relationship between t years after 2008, and the price P per pound will have some characteristics that we can identify.
<em>In 2008, i.e at t= 0, P = 0.51; this means the y-intercept is 0.51.</em>
<em>The coffee price is increasing by 0.18 every year; the slope is 0.18.</em>
Thus we have the equation

Answer:
Figure 1: 226
Figure 2: 111
Step-by-step explanation:
For the first figure, you will split it into two rectangles. You would do 28 x 7 for the first rectangle and get 196. Then, you would do 6 x 5 for the second rectangle and get 30. You would then add these two numbers and get the area of 226 ft^{2}}.
For the second figure, you split it into one triangle and two rectangles. For the triangle, you would do 3 x 6 and then divide that by 1/2, since it is a triangle, and you get 9. For the first rectangle, you would do 10 x 7 and you would get 70. For the final rectangle, you would do 8 x 4 and get 32. You would then add all these numbers up and get the area of 111 mm^{2}.
