Answer:
$110 and $30
Step-by-step explanation:
To solve this, we need to know the total share which is,
Then, you need to know the fraction of the share over the total, such that
So if to find how much that'll be of the $180 for the largest and smallest share,
Largest:
Smallest:
2miles=20km
20km/4=5km
5km=0,5mile
Runned 0.5 miles in total
The generic equation for a linear function can be expressed in the slope intercept form f(x) = mx + b, where m is the slope and b is the y intercept. For this problem we can first find the equation of the line. Then we substitute x = 7 to get the f(x) value, which is n at the point x = 7.
To find the equation of the linear function we first find the slope. Slope is defined as the change in f(x) divided by the change in x. As we are given a linear function, the slope at every point is the same. We can pick any two points known to find the slope.
Let's pick (3, 7) and (9, 16). The slope m is m = (16-7)/(9-3) = 9/6 = 3/2.
Now that we have the slope, we can plug in the slope and one of the points to find b. Let's use the point (3, 7).
f(x) = mx + b
7 = (1/2)(3) + b
b = 11/2
Now we can write the equation
f(x) = (1/2)x + 11/2
Plugging in x = 7 we find that f(7) = 9. n = 9
A. C(n)=10n+125
cost×number of buttons is equal to 10 cents times the number of buttons, plus the $125 cost of the button machine
