The cost for a company to manufacture "x"....
These statements tell you what X is. (The word cost refers to what the function will tell us. In other words C(x) = The Cost for the Company))
So as we keep going the problem goes onto:
.... bracelets
So the number of bracelets is X.
The function is: C(x)
And how functions work are quite simple. You plug in a number (x) and get out a number (y).
So, C(256) = 1536
So, they made 256 bracelets at a cost of 1536 dollars.
This is no different than if I said the function was:
C(x) = 6x
And then asked, what would the function equal when x = 256. It's the same thing, so don't let it trip you up!
Answer 1: 1536$
Answer 2: 256
Start with the slope formula.
m = y₂ - y₁ / x₂ - x₁
m = -6 - 3 / 5 - -2
m = -9 / 7
So the slope is -9/7.

Answer:
1. D) 1 9/20
2. B) 7/12
4. D) $50.00
Step-by-step explanation:
The working is as follows :
1. Mrs. Lang bought 3/4 pound of red grapes and 7/10 pound of green grapes. To find out how many are in total we have to add both values total.
3/4 + 7/10
The LCM of 4 and 10 is 20.
3/4 * 5 = 15/20
7/10 * 2 = 14/20
15/20 + 14/20 = 29/20 = 1 9/20
2. 1/3 + 1/4
The LCM of 3 and 4 is 12
1/3 * 4 = 4/12
1/4 * 3 = 3/12
4/12 + 3/12 = 7/12
4. Sharon spent 2/3 of her clothing allowance; she was given $75. All we have to do is find 2/3 of $25 :
2/3 * $75 = $50.00
There are no numbers with the letter “a” in them up until 1,000 [one thousand].
