Answer:
$1.99 is more expensive.
Step-by-step explanation:
Given:
One type of lace edging cost $0.80 per foot
Another type of lace edging cost $1`.99 per foot.
We need to find which is more expensive.
In $0.88 where one's place is 0.
In $1.99 where one's place is 1.
By comparing the one's place obviously $1.99 more expensive.
Hope you will understand the concept.
Thank you.

Answer:
Part A) 
Part B) 
Step-by-step explanation:
Part A) What is the explicit rule for the number of residents
we know that
In this problem we have a exponential function of the form
where
a is the initial value
b is the base
r is the rate
(1+r)=b
so
Let
y ----> the number of residents
x is the time in years
we have
a=1,000 residents
r=1%=0.01
b=(1+0.01)=1.01
substitute
Part B) How many residents will there be in the town in Year 10?
For x=10 years
substitute in the equation
The answer is 2.9 x 10^-3. You can just divide 5.8 and 2. You get 2.9. After when ever you are Dividing exponents you have to subtract the power. So (-6)-(-3) is just -3. So when you put it together you get 2.9 x 10^-3
Powers of 4 are like 4^1, 4^2, 4^3 and so on
remember that 4^x means 4 times itself x times for example
4^3=4 times iteslef 3 times=4 times 4 times 4
so the multipules of the powers of 4 are just 4 times of the previous
so we will list
4^1=4
4^2=16
4^3=64
4^4=256
4^5=1024
1024 is already more than 1000 so the list stops and is
1,16,64,256
