The density of ice cream is 0.65 g/cm3. The density of milk is 1.02 g/cm3. 80 cm3 of ice cream is mixed with 50 cm3 of milk to make a milkshake. What is the density of the milkshake rounded to 1 dp?​

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

if the probability is 1/12, 75 people will receive a $25 gift card
