Are you asking what it was decreased by? Because if you are just do 325-128 and you get 197
2520 bolts
Explained:
If it starts working at 3 PM, and makes 900 nuts at the rate of 600 nuts per hour. 900/600 =1.5. So it stopped making nuts at 4:30.
Then it started making bolts at a rate of 720 per hour for 3.5 hours between 4:30 and 8:00pm. 720 x 3.5 = 2520 bolts
The slope-intercept form is y = mx + b.
First find the slope.
m = (y1-y2)/(x1-x2)
m = (-2-5)/(-4-1)
m = -7/-5
m = 7/5
looking for b.
y = mx+b
5 = (7/5)(1) + b
5 = (7+5b)/5
25 = 7+5b
18 = 5b
b = 18/5
so the slope-intercept equation is
y = (7/5)x + (18/5)
To answer this question you would need to solve this inequality. The first step would be to combine all three terms on the left-hand side of the greater than symbol. By doing this you would have 50w > 250. To solve this inequality divide both sides by 50. The answer is w > 5. In words, this means the number of walnuts per spoonful is greater than five.
