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.
