In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
baker:
40 cookies (c) every hour (h)
Step 02:
independent and dependent variables:
40 cookies / hour
independent variable: hour (h)
dependent variable: cookies (c)
1. sentence:
The independent variable can have any value that we assign to it. Instead, the dependent variable depends on the value we chose for the independent variable.
2. hours (280 cookies):
[tex]280\text{ cookies }\cdot\text{ }\frac{1\text{ hour}}{40\text{ cookies}}\text{ = }7\text{ hours}[/tex]
7 hours
3. cookies (12.5 hours):
[tex]12.5\text{ hours }\cdot\text{ }\frac{40\text{ cookies}}{1\text{ hour }}=500\text{ cookies}[/tex]
500 cookies
4. Ordered pair (5, 200)
5 ===> 5 hours
200 ===> 200 cookies
Table and graph:
Process (This is how the values of "y" are calculated):
y = 40 * x = 40x
y1 = 40 * 1 = 40
y2 = 40 * 2 = 80
y3 = 40 * 3 = 120
y4 = 40 * 4 = 160
y5 = 40 * 5 = 200
y6 = 40 * 6 = 240
y7 = 40 * 7 = 280
y8 = 40 * 8 = 320
y9 = 40 * 9 = 360
That is the full solution.
