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.

Answer:
Let's assume the number is 100 now it is increased by 50% that means
100+ (50/100)*100
100+50=150
Now it is decreased by 25% that means
150- (25/100)*150
150–37.5=112.5
Total percentage increase ={(112.5–100)/100}*100
=12.5%
