Mark and Heather Starr are celebrating their 25th anniversary by having a reception at a local reception hall. They have budgeted $2,500 for their reception. If the reception hall charges a $60 cleanup fee plus $39 per person, find the greatest number of people that they may invite and still stay within their budget.

Step-by-step explanation:
Step one:
given data
total budget=$2500
we are told that the hall charges $60 for cleanup, the amount is a fix charge
and per person is $39
let the number of persons be x
The model for the situation is described by y=mx+c
Step two:
2500=39x+60
solve for x
2500-60=39x
2440=39x
divide both sides by 39 we have
x=2440/39
x=62.56
The greatest number of people that they may invite and still stay within their budget. is 62

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
Step by step solution :a-(1/2*h*(20+8))=0
Step 1 : 1 Simplify — 2 Equation at the end of step 1 : 1 a - ((— • h) • 28) = 0 2
Step 2 :Equation at the end of step 2 : a - 14h = 0
Step 3 :Equation of a Straight Line
3.1 Solve a-14h = 0
Graph of a Straight Line : Calculate the Y-Intercept :Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line a-14h = 0 and calculate its properties
Notice that when a = 0 the value of h is 0/-14 so this line "cuts" the h axis at h=-0.00000
h-intercept = 0/-14 = -0.00000 Calculate the X-Intercept :When h = 0 the value of a is 0/1 Our line therefore "cuts" the a axis at a= 0.00000
a-intercept = 0/1 = 0.00000 Calculate the Slope :Slope is defined as the change in h divided by the change in a. We note that for a=0, the value of h is 0.000 and for a=2.000, the value of h is 0.143. So, for a change of 2.000 in a (The change in a is sometimes referred to as "RUN") we get a change of 0.143 - 0.000 = 0.143 in h. (The change in h is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 0.143/2.000 = 0.071 Geometric figure: Straight LineSlope = 0.143/2.000 = 0.071 a-intercept = 0/1 = 0.00000 h-intercept = 0/-14 = -0.00000
