What is the checkbook balance if you have outstanding checks that totaled 223.85 an ending balance of 159.57 and outstanding deposits 147.96

Ending balance 159.57

outstanding checks: 223.85

outstanding deposits: 147.96

add ending balance and deposits

159.57+147.96=307.53

subtract new balance and outstanding checks

307.53-223.85=83.68 new ending balance

found it xd it ok yt

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
