The set builder notation of P is:

P= { x∈N | 1 ≤ x ≤ 100 }

Step-by-step explanation:

Set-Builder notation--

A set builder notation is a representation of a variable in the form of a set such that it states all the properties that are satisfied by it.It may also be used to represent a interval notation of some variable.

i.e. if x∈ (-10,3)

Then the set builder notation is:

{x ∈ R | -10 < x < 3 }

Here we are given a set P as: It consists of all natural numbers between 1 and 100, inclusive.

i.e. it takes all natural values from 1 to 100 and also it may take 1 and 100.

Hence, the set-builder notation of P is:

          P= { x∈N | 1 ≤ x ≤ 100 }

Answer:

72.9

Step-by-step explanation:

Fractions method:

because 90/100 is the same thing as 90%

That gives us 7290/100, from 81*90/100

Simplify: =729/10 = 72.9

Decimals method:

81*9 = 729, add in decimal and that's 72.9

Cross-multiplication:

90    100

?         81

This is read as 90 to 100, (as a ratio) so how many to 81? To solve, cross-multiply - 81*90=7290, then divide by 100 to get 72.9.

This is my first answer , hope it helped!

Answer:

The difference in the amount paid between the two contracts is $326.

Step-by-step explanation:

Given : An annual contract is $502.00/month with a 2-month penalty if you break the lease. The month-to-month contract is $615.00/month. Say you leave after 6 months.

To find :  How much is the difference in the amount paid between the two contracts?

Solution :

Annual contract: The annual contract means a contract for 12 months. There is a month penalty for breaking the lease. 

In our case the penalty is 2 month means if you left after 6 months, you will have to pay for 8 month.

Total paid = Monthly payment × 8

Total paid = 502 × 8 = $4016

Month-to-month contract: The payment is for actual month stayed.

You will only paid for the 6 months you stayed,

Total paid = Monthly payment × 6

Total paid = 615 × 6= $3690

To get the difference in the amount paid between the two contracts is

Difference = Annual contract - Month-month contract

Difference = 4016 - 3690 = $326

Therefore,The difference in the amount paid between the two contracts is $326.
