Answer:
The percentage decrease from the first week to the third week is 25 %
Step-by-step explanation:
The number of popcorn bags sold on the first week = 500 bags
The second week, they sell 50% more than the first week
So, the number of bags sold on the second week is
= 500 + 50% of 500
=
= 
= 500 + 250
= 750 bags
The third week, they sold 50% less than the second week
So, the number of bags sold on the third week is
= 750 - 50% of 750
= 
= 
= 750 - 375
= 375 bags
Now the percentage decrease from the first week to the third week is
=
= 
= 
= 25 %
Hello there! Your answer would be y = 0.5x - 3.
To find the equation, use slope intercept form, y = mx + b. <em>(m = slope, b = y intercept)</em>
For the slope, solve by subtracting the y values over the x values.
- 5 - - 3 / 0 - 4
- 2 / - 4
The negatives cancel out, and you are left with 0.5 as your slope. Plug that into m.
y = 0.5x + b
Now to find the y intercept. To do this, we can replace the x and y values into the equation and solve for b.
-5 = 0.5(4) + b
-5 = 2 + b
- 3 = b
so, the y intercept has a value of -3. Plug that in to the final equation.
y = 0.5x - 3
Hope this helps and have a great day!
