2. A 25-pound bag of fertilizer is on sale for $40. What is the price per ounce of the fertilizer? A $1.60 per ounce B $1.04 per ounce С $0.63 per ounce D $0.10 per ounce

109 is the nearest whole number/final answer! : )

30 people weigh 160 pounds or more

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
