REMEMBER WHEN I POSTED THIS QUESTION.
1 litre can of paint covers 11m squared. How many cans of paint would you need to cover a perfectly square ceiling that has a side length of 5.2 m?
If paint caosts $29.95 per can and there is a 12% tax. How much would it cost to paint the ceiling?
You had helped me and then I asked what the 1.12 was supposed to be and you answered it was 1.12=112% well my quesion asked for 12% tax not 112% so what would the cost be now?

The total is 100% of the price plus 12% tax. Therefore we multiply by 1.12 to find the price including the tax.
You could do two separate steps. Multiply the price by 0.12 and then add it to the price. 
oh ok thank you:)

You're very welcome. :)
