You are buying telephone equipment from a company whose prices are given in English Pounds currency. You need to purchase telephone equipment for 3 offices along with one complete switchboard system. Equipment for each office costs 100 Pounds, and the switchboard costs 333 Pounds. A 10% tax must also be added to the order. If the current exchange rate is $1.50 equals 1 Pound, how much will the system cost?

We will first calculate the total cost in pounds then convert to dollars.

1 - Equipment for three offices. The cost is 100 pounds per equipment.

Total cost of equipment = 3*100 = 300 pounds ... > I

2 - One switchboard. The cost is 333 pounds.

Total cost of switchboard = 333 pounds ... > II

3 - Total cost excluding taxes can be calculated by adding I and II as follows:

Cost excluding taxes = 300 + 333 = 633 pounds

4 - Tax is 10% of the cost.

Tax amount = 0.1 * 633 = 63.3 pounds

5 - Total cost including taxes = 633 + 63.3 = 696.3 pounds

6 - Convert the cost to dollars.

We know that 1 pound is equivalent to 1.5$. To know the equivalence of 696.3 pounds, just do cross multiplication as follows:

Cost in dollars = (696.3*1.5) / 1 = 1044.45$
