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$. To know the equivalence of 696.3 pounds, just do cross multiplication as follows:
Cost in dollars = (696.3*1.5) / 1 = 1044.45$
Answer:
There are 5 pigs on Aaron's farm
Step-by-step explanation:
1. Start with 40 animals
2. 1/10 of the animals are cows, so divide 40 by 10 and you will find that 4 of the animals are cows
3. 2/5 of the animals are chickens, so multiple 40 by 2 to get 80 and then divide 80 by 5 and you will find that 16 of the animals are chickens
4. Subtract the 4 cows and 16 chickens from the 40 total animals and you find there are 20 more animals that are neither cows nor chickens
5. Of the 20 remaining animals, 1/4 are pigs, so divide 20 by 4 and you will find that there are 5 pigs
