Answer:
or 12.5
Step-by-step explanation:
So if 25 - x items are sold, and they each cost x, we can write an equation for the revenue to be
y = (25 - x)x
The vertex of this equation will represent the maximum revenue. So we need to write this equation in vertex form so we can find the vertex.
Vertex from is
y = a(x - h)^2+ k,
where (h,k) represent the vertex.
the vertex form of this equation would be
And the vertex would be
This means the maximum revenue will occur when x = 25/2
Answer:
$360
Step-by-step explanation:
Given
Amount borrowed P = $4500 (principal)
Time T = 2 years
Rate R = 4
Simple interest formula is expressed as;
SI = PRT/100
Substitute the given parameters into the formula
SI = 4500×2×4/100
SI = 45×2×4
SI = 45×8
SI = $360
The amount of interest he will have to pay is $360
Answer: x = 8.4
Work: So, the goal of this equation is to get x by itself, and the first thing we need to do is get 22 out of that current side. To do that, we are going to add 22 on both sides, cancelling it on the side it's currently on. So, the new equation is 5x = 42. Now, we need to divide 5 on both sides, and like I said, I'll cancel on the side it's currently on. So, the answer is x = 8.4
