Question

Across the river from Ottawa, a store in Hull, Quebec, sells the same fence materials for $6.15 per foot. However, Quebec has a 7.5% PST that is calculated after the GST has already been added!

a) How much would this store charge for the fence materials for the tennis court before taxes?
b) Write and simplify an equation for the total cost, C, of a taxable item purchased in Quebec.
c) Use your equation to find the total cost for the fence materials at the store in Hull.

Answer 1

To calculate the cost of the fence materials before taxes in Quebec and then find the total cost at the store in Hull.

Step-by-step explanation:

a) To calculate the cost of the fence materials before taxes, we need to multiply the price per foot by the length of the fence. Let's say the length of the fence is L feet. The cost before taxes would be 6.15 * L.

b) The equation for the total cost, C, of a taxable item in Quebec is C = (1+GST)*(1+PST) * price of the item.

c) Using the equation from part b, we can substitute the price of the fence materials in and calculate the total cost for the fence materials at the store in Hull.
