Welcome! Today we're going to solve a business problem about oranges. Imagine someone bought 5 oranges for 2 dollars and 50 cents, but then sold each orange for only 10 cents. Let's find out how much money they lost and what percentage that represents. Now let's calculate how much money he got back from selling the oranges. He sold each orange for 10 cents. Since he had 5 oranges, we multiply 5 times 10 cents, which equals 50 cents or half a dollar. So he got back only 50 cents total. Now let's find out how much money he lost. He paid 2 dollars and 50 cents for the oranges, but only got back 50 cents when he sold them. To find the loss, we subtract what he got back from what he paid. 2 dollars 50 cents minus 50 cents equals 2 dollars. So he lost 2 whole dollars! Now let's calculate the percentage loss. To find a percentage loss, we divide the amount lost by the original cost, then multiply by 100. So we divide 2 dollars by 2 dollars 50 cents. This gives us 4 divided by 5, which equals 0.8. When we multiply 0.8 by 100, we get 80 percent. So he lost 80 percent of his money - that's a huge loss! So let's summarize what we learned today. The person bought 5 oranges for 2 dollars and 50 cents, but only sold them for 50 cents total. This means they lost 2 dollars, which is 80 percent of what they originally paid. That's a huge loss! This teaches us an important lesson in business: always try to sell things for more than you paid for them, or you'll lose money just like in this example.
