Acaterer charges $800 for a party of 25 guests. for a party of 60 guests, the cost is $1,430. enter a linear model that represents the total cost, c, as a function of g, the number of guests at a party.

  C = 18g +350

Step-by-step explanation:

The 2-point form of the equation of a line is useful for this. For points (x1, y1) and (x2, y2), the equation is ...

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

For points (25, 800) and (60, 1430), the line is ...

  y = (1430 -800)/(60 -25)(x -25) +800

  y = 630/35(x -25) +800

  y = 18x +350

Using the variables required by the problem statement, this is ...

  C = 18g +350

2.56 is the width of the garden

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
