Which of the following groups of numbers is in order from least to greatest? 0.54, , 40%
, 0.8, 94%
67%, , 0.8
0.54, 67%

0.8, 94% and 67%, 0.8 and 0.54, 67%

Step-by-step explanation:

Im a bit confused on what groups of numbers this question is refering too but I will try my best. So lets convert all the percents to decimals so, 40% = 0.4  

94% = 0.94   67% = .67. So, 0.54, 0.4 is not least to greatest. ( sorry if this was not what you ment but I just didn't get what groups )

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
