ANSWER:
Total monthly budget in dollar = $3665.
Now,
[i] Percent of taxes,
755/3665 × 100 = 20%
[ii] Percent of housing,
790/3665 × 100 = 22%
[iii] Percent of food,
350/3665 × 100 = 9%
[iv] Percent of savings,
700/3665 × 100 = 20%
[v] Percent of transportation,
245/3665 × 100 = 7%
[vi] Percent of clothing,
110/3665 × 100 = 3%
[vii] Percent of utilities,
185/3665 × 100 = 5%
[viii] Percent of entertainment,
110/3665 × 100 = 3%
[ix] Percent of other spending,
420/3665 × 100 = 11%
Regroup terms
Add 2x to both sides
Simplify 4 - x + 2x to 4 + x
subtract 4 from both sides
subtract -6 - 4.
Answer: x = -10
IQR = 6
First locate the median 
at the centre of the data arranged in ascending order. Then locate the lower and upper quartiles 
and 
located at the centre of the data to the left and right of the median.
Note that if any of the above are not whole values then they are the average of the values either side of the centre.
rearrange data in ascending order
15 16 ↓17 17 18 21 22 ↓23 25
↑
= 18
= 
= 16.5
= 
= 22.5
IQR = - = 22.5 - 16.5 = 6
