Answer:
c = 15d + 30
Step-by-step explanation:
Hey there!
This can be represented by an equation of a line, where the number of days is our x-values(d), and the price is our y-values(c).
The price for one day ($45) and the price for 4 days($90) are specific points on that line.
The points are (1, 45) and (4, 90).
We can first find the slope of the line:
- As the price rises 45, the days increase by 3
- Slope = rise/run
- Slope = 45/3
- Slope = 15
Now we can find the base price, by plugging the slope and a point into the equation y = mx + b.
Solve for b:
- y = mx + b
- 45 = 15(1) + b
- 45 = 15 + b
- 30 = b
The base price (b) is 30.
The equation is

Answer:
Proprortional Value is equal to 2/3 or 2:3
Step-by-step explanation:
4/6=2/3
6/9=2/3
8/12=2/3
10/15=2/3
14/21=2/3
Answer:
because this is a parallelogram
=> b - 10 + b + 10 = 180
<=> 2b = 180
=> b = 90
with b = 90 => b - 10 = 80
b + 10 = 100
we also have:
d = b + 10 => d = 100
c = b - 10 => c = 80
