AVprozaik [17]

Answer:

We suppose that a is the old price in cents

the total cost of 9.20 $ equals 920 cents

so we have 20 liters bought with the old price (a) and 10 liters with the new price (a + 2). This is translated into this equation where a is the old price therefore our quest to be answered

20 xa + 10 x (a + 2) = 920 (cents)

20 xa + 10 xa + 20 = 920

30 xa + 20 = 920

30 xa = 920 - 20

30 xa = 900

a = 900: 30

a = 30 (cents)

therefore the old price for 1 liter of petrol is 30 cents

(hope this helps can i plz have brainlist :D hehe)

erastovalidia [21]
So you're looking for 2 numbers you can divide to get ABOUT 4.1. This means you're going to estimate. First you can estimate that 4.1 is about 4 and then think what two numbers divide to give you 4? 8÷2 = 4 ... so now we can change it slightly to make the quotient a little higher and say
8.1÷2 = 4.05 That will round to 4.1 so you could say two numbers who's quotient is ABOUT 4.1 would be...
