I can't belive you're asking the Pit for an answer to a math question. Half of the people in here can't even figure out 1-1.
10% of £6.16 = X
1% of £6.16 = Y
Y * 2 = Z

X+Z

I think =/
well im stuck so thought why not ask the pit xD ive seen people do this before and got the correct answer soo

5.50

I don't know how to do the pound symbol

It's at 112% of what it started at. So, I divided 100 by 1.12, and got roughly 89.3 (the percentage that the previous price is of the current), and multiplied 6.16 by .893
112x = 6.16

Solve for x, multiply by 100, you get five fiddy, which is what above poster got.

Nope. 12% of 6.16 =/= 12% of the original price.

Divide £6.16 by 112, multiply by 100.
How much would that be in American money?

It's 4, right?

Sure is.

What rudi paid would be roughly \$10.77 USD, the new price is about \$12.05 USD

EDIT:

6.16 x 0.88 = £5.42

Not quite, but fairly close.

Almost the price of gas.
Original Value * 1.12 = £6.16
So 6.16 / 1.12 = original value

original value = £5.50.

You can check, as adding 12% to £5.50 = £6.16.

Basically a simplified version of what I did. We're right, I assure you, TS.

x(1.12)=6.16
x=6.16/1.12
