Gina has $175 with which to buy items at the bake sale at school. The graph shows the amount of money she has remaining and the number of items she purchases. Which answer choice best describes the domain and range of the function for this situation?

B

Step-by-step explanation:

You can delete options A and C, because there are multiple domains and ranges throughout the graph.

B or D?

Range - y axis

Domain - x axis

You can see that the x axis goes to 25 and y axis goes till 175.

Therefore the answer is B

Hope this helps you!

both equations and proportions are better.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
