Acatering firm charges a fixed cost for overheads and a price per person. it is known that a party for 20 people costs $557, whereas a party for 35 people costs $909.50. what is the fixed cost and the cost per person charged by the company?

The cost per person is 27.98 anything over the first 20 people go to 23.50

Step-by-step explanation:

909.50-557= 352.50

352.50 / 15 = 23.50

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
