First need to make an equation for each
x = Miles
y = Total Cost
Comp A: 120 + 0.20x = y
Comp B: 40 + 0.60x = y
cancel out the amounts to make it easier (Subtract 40 from each)
Comp A: 80 + 0.20x = y
Comp B: 0.60x = y
insert a problem for y to solve for x
80 + 0.20x = 0.60x
Your answer is 200 miles
Answer:
option a)
y = m(0.5) + 1.8
Step-by-step explanation:
Equation
<h3>
y = mx + c</h3>
represent the equation of straight line
here m = gradient of straight line
c = y-intercept
First find the gradient of the graph
<h3>
m = y2 - y1 / x2 - x1</h3>
= 4 - 3 / 4 - 2
= 1 / 2
Put the values in the equation of straight line
y =mx + c
4 = 1/2(4) + c
c = 2
y = 1/2x + 2
which is approximately equal to y = 0.5x + 1.8
Local Calls = 36
Distance calls = 20
Ratio would be: = 36/20 = 18/10 = 9/5
In short, Your Answer would be Option A
Hope this helps!
Answer:
Step-by-step explanation:
The term "for every" is a ratio indicator, meaning that every single time you use or do one thing then you must also do or use another thing. In this scenario, it is stating that every single time that you add a single cup of butter to the cookie recipe then you must also add three cups of flower to that recipe. This ratio always maintains its proportions meaning that if you add 2 cups of butter to the recipe you would need to add six cups of flower.
