Hi there!

Use slope formula to solve for the slope of the line:

Plug in points into the equation. We can use the points (0, -10) and (25, -5):

C
6x^2-13X-5=0
(3X+1)(2X-5)
3x-1=0
X=1/3. 2x-5=0. X= 5/2
Answer: 5
One half of 10 is 10/2 or 1/2(10)
10/2 = 5
1/2(10) = 5
Each bracelet is $5, this can be represented as 5b. (Where b is number of bracelets)
Each necklace is $8, this can be represented as 8n. (Where n is number of necklaces)
We know that the total money raised needs to be at least $100, but it can also be more than that.
So we know that 8n+5b will be greater than or equal too 100.
8n+5b ≥ 100
To do this multiply 1840 by 182. This gives you 334,880.
