Answer:
3
Step-by-step explanation:
Let's find how much money is left if Mrs.Smith buys a shirt.
52.50 - 39 = 13.50
13.50/4.50 = s
s = 3
Hope this helps :)
(1,2)
The solution is where the lines intersect so you can see they intersect at (1,2)
S=(n/2)(A+t)
x2 x2
2S=n(A+t)
--- --------
n n
2S n(A+t)
---=---------
n n
2S
---=A+t
n
.....2S
A=----- -t
......n
For this case what you must do is to graph both lines. (See attached graph) and see where both are cut.
We note that both lines are cut at the point (2,5)
Therefore the solution for f (x) = g (x) is x = 2
answer x = 2
