Hello there! An equation that can be used to find the total cost of the banquet is this:
225 + 50h + 25p = c
This is because "c" represents the total cost of everything, "h" represents hours, and "p" represents people. The $225 paid to rent a hall is a one-time price and does not go up. $50 is paid per hour to the DJ, and $25 is the amount per person for dinner.
1) Find the derivative

and

.
2) The equation of the tangent line is

, so at point (2,6):

and


-the equation of the tangent line at point (2,6).
Area of rectangle = LxW = 13x7 = 91
Area of triangle = bxh/2 = 7x7/2= 24.5
Total area= 91+24.5= 115.5 in^2
Answer:
Here,

substituting the value of 4y in eqn i fron eqn ii
so eqn i becomes

So

Thus,

...hope this helps:)
