Karen, james, frank, and dan were left an inheritance by their late grandfather. if karen receives one-eighth of the inheritance, james receives one quarter of the inheritance, frank receives three-eighths of the inheritance, and dan receives the remainder, what fraction of the inheritance does dan receive?

Count what fraction receive Karen, James and Frank in total:

since

Karen receives - ,

James receives - ,

Frank receives - ,

then .

All inheritance is the whole 1, then for Dan remains .

Dan receives one quarter of the inheritance.

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

step-by-step explanation:

8/7 = (1 * 7 + 1) / 7 = 1 + 1/7 = 1 1/7
