Cass decided to sell game programs for the Exeter-Andover field hockey game. The printing cost 20 cents per game program, with a selling price of 50 cents each. Cass sold all but 50 of the programs, and made a profit of $65. How many programs were printed? Letting p represent the number of programs printed, set up an equation that describes this situation. Then solve for p.

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

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
