At a sweater store, the price of a sweater is 20% more than the wholesale cost, plus a markup of $8. fund the rule for a linear function that describes the price of sweaters at the sweater store. use it to determine the price of a sweater with a wholesale cost of $24.50

The price of the sweater with the 20% increase and the markup of $8 is $29.4

because if you were to divide the price of the sweater $24.50 by 10 you would get  $2.45 cents time that by the 20% increase and you would have $29.4 without the markup included .

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

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
