Answer:
$143.60
Explanation:
To work this out you could work it out using two methods.
Method 1:
To work this out using method 1 you would first need to work out 10%. You can do this by dividing the amount of 179.50 by 10, this gives you 17.95. This is because as percentages are out of 100 and that 100% is the whole amount so to work out 10% you would divide 100% by 10 to give 10%.
Now that you have worked out 10% to work out 20% you would multiply 17.95 by 2, which gives you 35.9. This is because we had previosly worked out 10% and so to work out 20 you would multiply the 10% by 2.
The next step to find the new price you would minus 20% which is 35.9 from the original price of 179.50, this gives you 143.6. This is because now that we had worked out 20% we needed to find 20% off the original amount.
1) Divide 179.50 by 10.
2) Multiply 17.95 by 2.
3) Minus 35.9 from 179.50.
Method 2:
To work this out using the second method you would first need to convert the percentage into a decimal. You can do this by dividing the percentage of 20 by 100, this gives you 0.20. This is because percentages are out of 100.
The next step is to minus 0.20 from 1, this gives you 0.80. This is because you are trying to find the percentage decrease.
The final step is to multiply the original amount of 179.50 by 0.80, this gives you 143.6.
1) Divide 20 by 100.
2) Minus 0.20 from 1.
3) Multiply 179.50 by 0.80.
