Dave is his grandmother make trail mix his grandmother asks him to add 1/5 cup of fruit for every 1/3 cup of nuts. to satisfy his grandmother's request, drave must mix cups of fruit for a single cup of nuts

To satisfy his grandmother's request, drave must mix 3/5 cups of fruit for a single cup of nuts

It is given that:

1/5 cup of fruit is required for every 1/3 cup of nuts while making a trail mix.

Hence,

1/3 cup of nuts= 1/5 cup of fruit

This means that:

1/3 ×3 cup of nuts=1/5×3 cup of fruit

i.e.  1 cup of nuts=3/5 cup of fruit

                   Hence, the answer is:

     3/5 cups of fruit is required for single cup of nuts.

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
