1. Harley bought a motorbike for $25000, then later sold it at a 20% loss. What was his selling price?
25000 * 0.20 = 5000
25000 - 5000 = $20000 ANSWER
or
25000 * 0.80 = $20000 ANSWER
2. It cost Diana $60 to make a set of drawers. For how much would she need to sell them to make a profit of 15%
60 * 0.15 = 9
60 + 9 = $69 ANSWER
or
60 * 1.15 = $69 ANSWER
3.If 800 sheep cost $4000, how many can be bought with $3000
$4000 / 800 sheep= 5 $/sheep
$3000 / 5$/sheep = 600 sheep ANSWER
4. Divide $120 in the ratio 3:5
total parts = 3 + 5 = 8
120/8 = 15
3(15):5(15) = 45 : 75
5. Aaron, Karen and Tarryn share 72 marbles in the ratio 1:2:6. How many more marbles will Tarryn receive than Aaron?
total parts = 1 + 2 + 6 = 9
72/9 = 8
1(8) : 2(8) : 6(8) = 8 : 16 : 48
48 - 8 = 40 marbles ANSWER
25000 * 0.20 = 5000
25000 - 5000 = $20000 ANSWER
or
25000 * 0.80 = $20000 ANSWER
2. It cost Diana $60 to make a set of drawers. For how much would she need to sell them to make a profit of 15%
60 * 0.15 = 9
60 + 9 = $69 ANSWER
or
60 * 1.15 = $69 ANSWER
3.If 800 sheep cost $4000, how many can be bought with $3000
$4000 / 800 sheep= 5 $/sheep
$3000 / 5$/sheep = 600 sheep ANSWER
4. Divide $120 in the ratio 3:5
total parts = 3 + 5 = 8
120/8 = 15
3(15):5(15) = 45 : 75
5. Aaron, Karen and Tarryn share 72 marbles in the ratio 1:2:6. How many more marbles will Tarryn receive than Aaron?
total parts = 1 + 2 + 6 = 9
72/9 = 8
1(8) : 2(8) : 6(8) = 8 : 16 : 48
48 - 8 = 40 marbles ANSWER
-
1. cost price of motorbike = 25000
loss = 20%
loss = 25000*20/100 = 5000
selling price = cost price - loss
=25000 - 5000 = 20000
2.
cost = 60
profit = 60*15/100 = 9
selling price = cost + profit
=60+9 = 69
3.
cost of 800 sheep = 4000
cost of one sheep = 4000/800 = 5
No. of sheep bought on 3000 = 3000/5 = 600
4.
3x + 5x = 120
8x = 120
x = 120 /8 = 15
3x = 3*15 = 45
5x = 5*15 = 75
5.
1x + 2x +6x = 72
9x = 72
x = 72/9 = 8
Aaron received ,1x = 1*8 = 8
Karen received, 2x = 2*8 =16
Tarryn receoved , 6x = 6*8 =48
loss = 20%
loss = 25000*20/100 = 5000
selling price = cost price - loss
=25000 - 5000 = 20000
2.
cost = 60
profit = 60*15/100 = 9
selling price = cost + profit
=60+9 = 69
3.
cost of 800 sheep = 4000
cost of one sheep = 4000/800 = 5
No. of sheep bought on 3000 = 3000/5 = 600
4.
3x + 5x = 120
8x = 120
x = 120 /8 = 15
3x = 3*15 = 45
5x = 5*15 = 75
5.
1x + 2x +6x = 72
9x = 72
x = 72/9 = 8
Aaron received ,1x = 1*8 = 8
Karen received, 2x = 2*8 =16
Tarryn receoved , 6x = 6*8 =48
-
1. $25,000 * .8 = $20,000
2. $60 * 1.15 = $69
3. 800 * 3/4 = 600
4. 120 / (3+5) = 15, so 3*15 : 5*15 or 45 : 75
5. 72/9 = 8. So Aaron: 8, Karen: 16, Tarryn: 48. 48-8 = 40
2. $60 * 1.15 = $69
3. 800 * 3/4 = 600
4. 120 / (3+5) = 15, so 3*15 : 5*15 or 45 : 75
5. 72/9 = 8. So Aaron: 8, Karen: 16, Tarryn: 48. 48-8 = 40

1. 25,000 x .20 = 5,000 , 25,000- 5,000 = 20,000
2. 60 x .15= 9, 60 +9=69 her profit is $9
3. $1,000=200 sheep, so $3,000=600 sheep
