Nice of you to offer 50 points
the constant of proportinality is the sloep or

x is independent variable and y is dependent variable
the independent variable influences the value of the dependent variable
in this case, the number of months influences the amount of money saved
to find the slope, you do
x=number of months
y=amount
we have
4months, $50
8 months, $100
18 months, $225
or
(x,y)
(4,50)
(8,100)
(18,225)
we can compare
the slope between the points (a,b) and (c,d) is
(d-b)/(c-a)
we can take the slope between any 2 points (assuming the slope is the same, which it is)
(4,50) and (8,100)
slope=(100-50)/(8-4)=50/4=25/2=12.5
the slope is 12.5
2nd option is the answer
7: $200<3x-y(28) where x represents each kids money out of it and y represents the parents pay.
8: 7.00>(is greater then or equal to) 0.75X + 1.29Y where X is the amount of bagels and Y is the amount of cream cheese containers.
9: $25 + $75>4X where X is the shirts
10: 720-120>(greater then or equal to) 32X where X is the number of people in each row
11: 2400= 2100+ X(1/20) where X is the value of all things sold.
12: 2000<(X7)-668 where X is the amount of cans in one day.
13: 100> 7X - 10Y where X equals the amount of months and Y equals the amount of CD's
14: $80 - $22> (greater than or equal to) 17X where x equals the amount of shirts.
first off sorry it took so long to answer, these long word questions are time consuming and i havent done them in a while so i had to refresh my memory, secondly the equations all end where i say the word "where", thirdly i am absolutely sure of all these answers except for the first one, the first one i am pretty sure i still got it but not 100%.
hope this helps.
Answer:

B. 12 boys
Answer:
6
Step-by-step explanation:
18.3/3.05=6
18.3 / 6=3.05
Answer:
3m - 4
Step-by-step explanation:
Divide.
(15mn)/(5n) = 3m
(-20n)/(5n) = -4
3m - 4 is your answer.
