Answer:
Step-by-step explanation:Write as two points in terms of: (number of people, cost in $)
�
(15,120) and (25,200)
�
Find the equation of the line using:
�
m = (y2 – y1) / (x2 – x1) and y = mx + b
�
Equation:
�
Y = 8x
�
plug in x = 40
�
y = 8(40) = 320
�
A party of 40 people will cost $320.00.
�
Slope:
�
m = 8 $/person
�
For every person that attends the party, the caterer’s bill increases by $120.00.
�
y-intercept: 0
�
(0,0)
�
This tells us that if no one attends the party, the caterer’s bill will be $0.00. So the
�
caterer has no base cost they charge to caterer a party.

500ml : 2000ml
5 : 20
<u>1 : 4</u>
<u></u>
2] 
× 500
= 250ml
