Answer :
The total cost of the used cell phone in Canadian dollars is C$130.16.
Su Mei should buy the used cell phone because it is cheaper than the new cell phone.
Which phone should Su Mei buy?
The exchange rate is the rate at which one unit of a currency is exchanged for another currency. For example, if the exchange rate of the US dollar and the Canadian dollars is 1.00903. It means that 1 unit of the US dollar would buy 1.00903 of the Canadian dollars.
The first step is to determine the total cost of the used cell phone in US dollar. The total cost would be the sum of the used cell phone and the shipping cost.
Total cost of the used cell phone = $99 + $30 = $129
The next step is to convert the cost of the used cell phone that is priced in the US dollar to Canadian dollars.
129 x 1.00903 = $130.16
