Answer:
12 dollars
Step-by-step explanation:
60 divided by 5=12
Answer:
To find the price per spoon of brand A, divide the cost by the amount of spoons:
1.99 / 25 = 0.0796
Repeat this process for brand B:
3.89 / 42 = 0.0926
Brand A, at $0.08 a unit, is the better buy of brands A and B.
1. V = x (12 - 2x) (8 - 2x)
The zeros are 0, 6, and 4
2. dV/dx = x(12 - 2x)(-2) + (8 - 2x)(12-4x) = 0
x = 4.9
3. If V = 12 = x (12 - 2x) (8 - 2x)
x = 0.13, 3.65, 6.22
4. If we increase the dimensions of the cutout until 4.9, the volume will also increase, after that, the volume will decrease.
5. V = x (q - 2x) (p - 2x)
