Answer:
360
Step-by-step explanation:
The given digits are 1,2,3,4,5,6.
So, total number of digits = 6.
We need to find the number of different ways to form four-digit numbers using the digits, without repetition.
Total ways for first place = 6
After selecting 1 digit the number of remaining digits is 5. So,
Total ways for second place = 5
Similarly,
Total ways for third place = 4
Total ways for forth place = 3
Total number of ways = 
Therefore, 360 four digit numbers are possible.
Step-by-step explanation:
carly had nothing, amount of money = £0
amy gave her £7 and brad gave her £5,
carly now has £5 and £7
amount of money of carly= £7 + £5
= £12
you are told that they all have the same amount of money and you know that carly has £12. so:
amy has £12, brad has £12 too.
If amy has £ 12 now after giving away £7, then: let x be the initial amount of money amy had,
x - 7 = 12
x = 12 + 7
x = 19
thus, amy had £19.
