y=45x+200
y is the total cost, x is the number of months, and 200 is the start.
Step-by-step explanation:
by having two equations that have the same point, you can set the two equations equal to each other
y = 12x + 3, y = x + 1
12x + 3 = x + 1
11x = -2
x = -2/11
when you find the the x value, plug it back into either one of the equations
y = x + 1
y = (-2/11) + 1
y = 11/11 - 2/11
y = 9/11
the point (solution):
(-2/11, 9/11)
This is an increase and it increased by 40% because the difference between 140 and 100 is 40 which is 40% of 100.

Step-by-step explanation:
Answer:
1 3/20
Explanation:
Find the lowest common denominator of both fractions, which is 20.
2/5 = x/20. Find the value of x and that is 8.
3/4 = y/20. Find the value of y and that is 15
Add 8/20 and 15/20 and that gives you 23/20. This is an improper fraction so divide 23 by 20, which is 1 3/20
