Yuto is correct because he isolated the variable correctly and reversed the inequality symbol.
x < 3
It can be too late to save for retirement. You want to begin saving at least 45 years before you plan to retire.
<h3>When to start savings for retirement?</h3>
Retirement is when labour stops working at a regular job. When a person retires, they would have a reduced source of income. This is why it is important to save for retirement. The earlier one starts to save for retirement, the more money the person would have when they retire.

Since a $5 decrease in price increases customers by 20 we can say that we have two points:
(125,100) and (120,120), from these we can find the slope or rate of change of customers as a function of price...
m=20/-5
m=-4
m=-4
c(p)=-4p+b, now we can use (125,100) to solve for b
100=-4(125)+b
100=-500+b
600=b, so our number of customers as a function of price is:
c(p)=600-4p
Revenue will simply be the number of customers times the price charged per customer...or p*c(p):
r(p)=600p-4p^2
We can find price that creates maximum revenue by finding when the derivative is equal to zero...
dr/dp=600-8p
dr/dp=0 only when
0=600-8p
8p=600
p=75
So the price that maximizes revenue is $75.
Answer:
False
Step-by-step explanation:
It depends on the distance and the curvature of the path. It is a straight line between endpoints and the length is a reasonable multiple of the full length of the tape measure then the tape measure is more accurate. If on the other hand the terrain is rugged and/or curvy then there isn't much to choose between the two. I think you are intended to answer false. The question leaves a lot to be desired.
Work shown above! Answer is √(11/8)
