Answer:
41235
Step-by-step explanation:
There are 120 five-digit numbers that can be made from the digits 1, 2, 3, 4, 5 if each digit is used once in the number,
The total number of times where each number will occur or be at first place is calculated as:
4! = 4 × 3 × 2 × 1
= 24
Hence,
24th number = The last number where 1 is at first place
We can write this out as:
12345
12354
12435
12453
12534
12543
13245
13254
13425
13452
13524
13542 e.t.c.
48th number = The last number where 2 is at first place
72nd place = The last number where 3 is at first place.
This means, the 73rd number is the first number where 4 is at first place.
Therefore, the 73rd number based on pattern is 41235
Answer:
$618.95 rounded up. 0.004c
£388.09 on rent and $230.84 food
We can round up and state $619 to nearest tenth.
Or leave as non rounded Total $618.93
Step-by-step explanation:
27% of 1,437.40=388.09
1,437.40 - 388.09 = 1049.31
22% of 1049.31 = 230.8482
$230,84 Shown here, as not round up or down as 230.84 as £388.09 was not rounded up from 388.098.
= $618.95 rounded up. 0.004c
