# Thread: Finding amount before taxes..

1. ## Finding amount before taxes..

a) Cody has just bought a gift in Nunavut and paid $474.97. What exactly was the retail price before taxes? Note that Nunavut charges GST of 5% b) Siran has just bought a gift in Prince Edward Island and paid$502.14.
What exactly was the retail price before taxes?
Note that Prince Edward Island charges GST of 5% and PST of 10% (and P.S.T is charged on top of G.S.T).

Any help?

2. If you bought something for $250 and was charges 5% tax, then tax amount = 250 * .05 = 12.50; so total =$262.50

So question would be: if you paid $212.50 including 5% tax, what was the retail price before taxes? Apply that to your 2 problems. 3. Originally Posted by johnny4johhny99 a) Cody has just bought a gift in Nunavut and paid$474.97.

Price-of-item + taxes = Total-amount-paid
taxes = 5% or 0.05 times price-of-item

Total-amount-paid = Price-of-item + (price-of-item)x0.05

Total-amount-paid = Price-of-item x (1.05)

If you know the Total-amount-paid & the tax rate, then

Price-of-item = $\dfrac{ \text {Total-amount-paid}}{ 1.05}$

(NOTE: the tax amount will ALWAYS be rounded up!)

b)
Cost-of-Item(including GST) = $\dfrac{502.14}{1.10}$

Cost-with-no-tax = $\dfrac{ \left( \dfrac{502.14}{1.10} \right)}{\left(\dfrac{1.05}{1}\right)}$
