The cost of petrol rises by 2 cents a liter. Last week a man bought 20 liters at the old price. This week he bought 10 liters at
In-s [12.5K]

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

Answer: $35.35

Step-by-step explanation:

Facts

3 items

item 1: 8.95

item 2: 11.49

item 3: 12.75

6.5% sales tax

8.95+11.49+12.75= 33.19

Step 2: Apply the sales tax

6.5% of 33.19 = 2.15735 --> approximatley $2.16

Step 3: Add the sales tax amount to the total cost of the items to find the final total cost.

$33.19+$2.16= $35.35  

Hence the answer is B
