Boys did 1/8 of his homework at school and 1/16 of his homework on the bus ride home. Boyd plans to do the rest at home. What percent of Boyd's homework does he plan to do at home?

81.25%

Step-by-step explanation:

Let the total homework of a boy be x

Part of homework done at school= x

Part of homework done at bus ride home= x

Part of homework done = x + x

Part of homework done =

Part of homework left to be done at home= x -

Part of homework left to be done at home=

Percentage of homework of the total work is to be done at home=  × 100%

Percentage of homework of the total work is to be done at home= 81.25%

Hence, the correct answer is 81.25%

the correct answer is 828.07

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
