Ignore the "$".

Jenny's grandmother has $24$ cats. Seventeen of the cats do not catch mice. Ten of the cats have black fur. What is the smallest possible number of cats that do not catch mice that have black fur?

3

Step-by-step explanation:

Note that  24  - 10  =  14  don't have black  fur

And suppose  that these 14 are part of the 17 that don't catch mice

Then3 that catch mice  must also have black furand this is the smallest number that do not catch mice but have black fur

3

Step-by-step explanation:

For the least number of cats that do not catch mice and have black fur, the cats with black fur must catch mice. 24 - 17 = 7 cats that catch mice. So, we can only assign 7 cats that have black fur and catch mice. The rest, 10-7 =3, must not catch mice. Therefore, the smallest possible number of cats that don’t catch mice and have black fur is 3.

I hope this helps! :)

step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
