Answer:
1/2
Step-by-step explanation:
2/3 (2/8 + 4/8) =
First simplify what is inside the parentheses
2/8+4/8 = 6/8
Replace with 6/8
2/3 (6/8) =
Then multiply
2*6 =12
3*8 = 24
12/24
Divide top and bottom by 12
1/2
So $25 - $17.35 = $7.65
7.65÷ 17 = 45
45 = 45 min
Answer: the old price for 1 liter is $0.3
Step-by-step explanation:
Let x represent the old price for 1 liter of petrol.
Last week a man bought 20 liters at the old price. This means that the total amount that the man paid for 20 liters is 20x.
The cost of petrol rises by 2 cents a liter. This means that the new price per liter is x + 2/100 = x + 0.02
This week he bought 10 liters at the new price. This means that the total amount that the man paid for 10 liters is
10(x + 0.02)
= 10x + 0.2
Altogether, the petrol costs $9.20. This means that
20x + 10x + 0.2 = 9.2
30x + 0.2 = 9.2
30x = 9.2 - 0.2
30x = 9
x = 9/30
x = 0.3
