Answer:
60
Step-by-step explanation:
First, find the area of the square as it the missing piece wasn't missing.
8 x 9 = 72
Then, find the area of the missing section.
3 x 4 = 12
Finally, subtract 12
from 72
and you get 60
Here, we just use the following x values and put them into the equation.
y = - 0.05x + 16
y = -0.5(0) + 16
y = 16
y = - 0.05x + 16
y = -0.5(160) + 16
y = -80 + 16
y = -64
y = - 0.05x + 16
y = -0.5(320) + 16
y = - 160 + 16
y = -144
Now, to set up the table, you could list the x values and the y values.
x values :- 0,160, 320
y values:- 16, -64, -144
I think you have to count 85 and go down like 85 86 87so the answer is 15
