Samantha makes 8 origami animals in 1 hour. fernando makes 7 origami animals in 1 hour. how many total animals will samantha and fernando make in 3 hours?

24 + 21 = 45

Step-by-step explanation:

So if Samantha makes 8 in 1 hour that means she will make the same amount the next hour and the next hour making 24 by the third hour.

Same with her friend Fernando making 21 by the third hour.

Adding them together to get the total makes 45 cute origami animals.

step-by-step explanation:

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
