Answer:
The total number of combinations is 2,358,720,000
Step-by-step explanation:
For the letter part of the ID we have 3 letters out of a space of 26 possible letters (a-z), and they can't repeat. For the number part we want to group 5 numbers out of 10 possible algarisms (0-9).So we can make an arrangement for the letters and one for the numbers and multiply them. The arrangment can be done using the following formula:
A(n,k) = (n!)/(n-k)!
Where n is the total number of possibilities and k is the size of the group.
For the letters:
A(26,3) = (26!)/(26-3)! = (26!)/(23!) = (26*25*24*23!)/(23!) = 26*25*24 = 15600
For the numbers:
A(10,5) = (10!)/(10 - 5)! = 10!/5! = (10*9*8*7*6*5!)/(5!) = 10*9*8*7*6*5 = 151200
The total number of combinations is the product of both, so:
combinations = 15600*151200 = 2,358,720,000
Hi I want to help u but can u take a pic :)
Given:
Credit card balance : 650
APR: 19.85%
Minimum payment : 20
I used an online Credit card calculator to solve for the total amount that Jose will pay for his purchase and how long it would take him to pay it.
It would take Jose 4 years to pay off his stereo.
4 years x 12 mos/yr = 48 months
48 mos x 20 min. pyt = 960 total amount paid.
960 - 650 = 310.
Had Jose opted to pay in cash, he would have been able to save 310.
