Answer:
Rita must work 50 days to save at least $25.
Step-by-step explanation:
The amount Rita earns per hour = $10
The saving percentage = 5%
So, the savings of Rita per hour = 5% of $10
⇒5% of $10 =
or Rita saves $0.5 per hour.
The amount she wants to save at minimum = $25
So, let she works at the minimum of k Days.
⇒
or,
The number of hours she has to work = 50 days
Hence, Rita must work 50 days to save at least $25.
Answer:
y=[-2]x[+][5]
Step-by-step explanation:
m= -2
Using the point (1,3) Find the value of b
3= -2(1)+b
3= -2+b
+2 +2
---------
5=b
y= -2x+5
The base case is the claim that
which reduces to
which is true.
Assume that the inequality holds for <em>n</em> = <em>k </em>; that
We want to show if this is true, then the equality also holds for <em>n</em> = <em>k</em> + 1 ; that
By the induction hypothesis,
Now compare this to the upper bound we seek:
because
in turn because
