A, I was challenged by the customer service....
Answer: price of a large van = $35000
price of a small van = $30000
Explanation:
Let the price of a large van = x
Let the price of a small van = y
Since A receives 5 large vans and 2 small vans for a total cost of $235,000. Location B receives 2 large vans and 3
small vans for a total cost of $160,000. This can be written as:
5x + 2y = 235000 ........ i
2x + 3y = 160000 ........ ii
Multiply equation i by 2
Multiply equation ii by 5
10x + 4y = 470000 ..... iii
10x + 15y = 800000 ..... iv
Subtract iii from iv
11y = 330,000
y = 330000/11.
y = 30,000
From equation I,
5x + 2y = 235000
5x + 2(30000) = 235000
5x + 60000 = 235000
5x = 235000 - 60000
5x = 175000
x = 175000 / 5
x = 35000
Therefore, price of a large van = 35000
price of a small van = 30000
Answer:
Dogs
Dog owners normally have a stronger immune system, helping them to stay well and spend less time getting over sicknesses and diseases. Nothing beats a long walk with your four-legged friend on a fresh, spring morning. Or seeing the joy on their faces when you pick up a ball and they know it’s playtime in the local park! Even relaxing at home feels better in each other’s company.One of the unexpected benefits of dogs is the way they add to your social life. Going to obedience classes, saying ‘hello’ to other dog walkers when you go to the park with your canine companion – there are dozens of ways in which your dog makes you more sociable.
Your new puppy will get you out and about, trying things you never considered before and introducing you to new experiences. Whether you’re going to a new pet shop or exploring a new area to make your dog’s daily walk more interesting, you’re bound to see new people all the time. You’re unlikely to stop for a chat with a stranger when you’re walking by yourself, but we all know how easy it is to talk when our dogs want to make friends. And, no matter how different we are, we have something in common – our highly sociable, friendly dogs!One of the most fascinating benefits of dogs is their amazing ability to make us feel calm - and that has a brilliant effect on our health.
Hope this is good enough...
