Cheryl is organizing her movie collection. If each movie case is 3/4 inch wide, how many movies can fit on a shelf 5 1/4 feet wide?

3

Step-by-step explanation:

size of the shelf= 5 1/4 = 21/4

size of movie case = 3/4

The number of movie cases that will fit in a 5 1/4 ft shelf = 21/4 ÷3/4

= 21/4 *4/3

= 7

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

multiple all that
