Q2 My Dog ate my homework!

I fell asleep while doing my Math homework.

When I woke up, I saw my file open and my dog is eating my homework!

I fought with it and managed to take back some parts of my HW!

And this is all that remains.

Please help me to reconstruct my HW. I can't even see the question. Only the diagram and the final answer remains!

1b)$40900 - $10700 = $30200
c)0.02x900=$180
0.05x21200=$1060
$1060+$180=$1240
d)1240/30200 x100 =4.105960625
=4.11%

Question 2
(2i) Total relief =3000+1000+2000+2000+2000+9600 = $19600
(2ii)48000-19600 = $28400
(2iii)12/100 ×28400 = $3408


Question 3
3)Total relief = 3000+2000+3000 = $8000
40000-8000 = $32000
10/100×10000 = $1000
15/100×22000 = $3300
1000+3300 = $4300

Heymath Income Tax Assignment

1a) his total reliefs= $3000+$2500+$(2600x2)
=$ 10700

b) chargeable income= $40900- $10700
= $30200

c) income tax first $9000 = $180next $21200 @ 5% = 5% x 21200
= $1060
total: $180 +$1060= $1240

d) 1060/30200 x 100% = 3.5 %
2. a)(i) total relief = $3000+$1000+$2000+$4000+$9600
= $19600
(ii) $4000x12 = $48000 per year
chargeable income = $48000 -$19600 = $28400

(iii) tax payable =12% x 28400 = $3408

3. total relief = 3000+2000+1500+1500= 8000

chargeable income = 40000-8000
= $ 32000
first 10000= $3200 next 28800 @15% = $4320

his income tax= $3200+ $4320=$7520

Income tax :)

1a. His total reliefs= 3000+2500+2(2600)= $10700
b. His chargable income = 40900-10700=$30200
c. First: 9000(2/100)=$180
Next: 21500(5/100)=$1075
His total income= 180+1075= $1255
d. The percentage is: 100%× (1225/30200)= 4.06%

2.a. His total reliefs for the year= 3000+1000+2000+2000×2+9600=$19600
b. His annual chargeable income= 4000×12-19600=$28400
c. The total charge is: (12/100) ×28400=$3408

3. His chargeable income= 40000-( 3000+3000+2000)=$32000
First: 10000×(10/100)=$1000
Next: 22000×(15/100)=$3300
His income tax is :1000+3300=$4300
