Which explanation correctly solves this problem? a golf club has 85 golfers in a golf tournament. the golfers will ride in golf carts. each cart holds 4 golfers. how many golf carts will the club need for all the golfers? 85 ÷ 4 = 21 with 1 left over. they will need 22 golf carts. 85 ÷ 4 = 21 with 1 left over. they will need 21 golf carts. 85 ÷ 4 = 21 with 1 left over. they will need 21142114 golf carts.

The answer is A. 85/4=21 with 1 left over. They will need 22 golf carts.

hope this !

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
