The cost function for Shannon’s new clothing store where she sells T-shirts is C = $8.75 + 925. What is the slope of the cost fu
1 answer:
Answer:
The slope of cost function for Shannon's new store is 8.75.
Step-by-step explanation:
The given cost function for Shannon's store is :
.....1
where C is the cost and n is the number of T-shirts sold.
The general form of equation of a line is given as :
.....2
where y is the y-coordinate , m is the slope of the line , x is the x-coordinate and c is the y-intercept.
On comparing equation 1 and 2, we can conclude that :
y = C ;
x = n ;
c = 925 ;
and m = 8.75 ;
Thus, slope of Cost function is 8.75 .

Answer:
The numbers are 18, 13, and 72.
Step-by-step explanation:
Let the three numbers be represented by <em>a, b</em>, and <em>c</em>.
The sum of the three is 103. Thus, we can write that:
The second number is five less than the first. So:
And the third number is four times the first. So:
Substitute:
Solve for <em>a</em>. Combine like terms:
Add five to both sides:
And divide both sides by six. Therefore:
So, the first number is 18.
Since the second number is five less than the first, the second number is 13.
And since the third number is four times the first, the third number is 72.
