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
Let no. of adult tickets be x and senior citizen tickets be y.
x + y = 556
22x + 12y = 8492
Solving by simultanous equations,
x = 182 adult tickets
y = 374 senior citizen tickets
Answer:
a(46) = -1.5 + 0.2(45) = -1.5 + 9 = 7.5
Step-by-step explanation:
Each term of this sequence is 0.2 greater than the previous term. The formula for this arithmetic sequence is
a(n) = -1.5 + 0.2(n - 1)
and so the 46th term is:
a(46) = -1.5 + 0.2(45) = -1.5 + 9 = 7.5
