Please help. The question reads...The refrigerator was repaired for $176. If GST is 10%, how much was GST? Is the answer$17.60 or $16. Can some one please tell me which answer is right and why the other answer is wrong. GST is a Tax added on to the purchase price. If$17.60 is right wouldnt the repair then cost $193.60? 2.

I don't know what GST is but I assume they are asking to find $\displaystyle 10$% of $$\displaystyle 176. A percentage is always out of 100 hence you can multiply through in that format: \displaystyle \frac{10}{100} \times 176 = 17.6 When asked to calculate percentage, you can also change it to decimal and multiply through. \displaystyle 0.1 \times 176 = 17.6 The answer is$$\displaystyle 17.60$. 3.

$176 is the total after tax is added hence as a percentage value it is 110% which is 1.1 as a decimal number. To get the value before tax, we need to find the 100% value hence we cross multiply.$\displaystyle \frac{176 \times 1}{1.1} = 160$Therefore the value before tax is added is$160.
