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. :-)
To calculate the number of cans of paint required to cover the ceiling, you need to find the area of the ceiling and divide it by the coverage of one can of paint.
Given:
- One can of paint covers 11 square meters.
- The side length of the ceiling is 5.2 meters.
First, find the area of the ceiling:
Area of the ceiling = Side length of the ceiling * Side length of the ceiling
= 5.2m * 5.2m
= 27.04 square meters
To calculate the number of cans of paint needed:
Number of cans = Area of the ceiling / Coverage of one can of paint
= 27.04 square meters / 11 square meters
≈ 2.46 cans
Since you can't buy a fraction of a can, you would need to round up to the nearest whole number. Therefore, you would need 3 cans of paint.
Now let's calculate the total cost including tax:
Given:
- The cost of one can of paint is $29.95.
- The tax rate is 12%.
To calculate the cost of one can of paint including tax:
Tax amount on one can = 12% of the cost of one can of paint
= 12/100 * $29.95
≈ $3.59
Cost of one can of paint including tax = Cost of one can + Tax amount on one can
= $29.95 + $3.59
≈ $33.54
To calculate the total cost for 3 cans of paint, you need to multiply the cost of one can including tax by the number of cans:
Total cost = Cost of one can including tax * Number of cans
= $33.54 * 3
≈ $100.62
Therefore, it would cost approximately $100.62 to paint the ceiling with 3 cans of paint, including a 12% tax.
