Question

A food supplier bought coffee at $8 per kilogram. He sold 20.5 Kilograms of coffee at $2.50 per 200 grams. How much money did he earn?

Answer 1

I think its 200×20.5 and then you'll get your answer

Answer 2

Well, so he bough coffee at $8 per kilogram.

So, he spend $164 to get 20.5 kg, and then he sold the 20.5 kg of coffee at $2.50 per 200 grams.
So, 20.5 kg in grams would be 20,500 g of coffee.

Then we proceed to multiply to see how many money he earned.

20,500g x $2.50/200g = $256.25

Then if you want to know how much profit he get, you need to subtract the amount of money he gets minus the amount of money he spend.

$256.25 - $164 = $92.25

So the profit is $92.25
