Question

How much do 10 pieces of candy cost of 1000 pieces cost $20

Answer 1

Assuming that there is a constant price, we can see that if a 1000 pieces cost $20, 10 pieces cost x dollars. The ratio is 1000/20=10/x. Going further, we can see that 500x=10. x = 1/50 dollars or x = 2 cents. 

Answer 2

Answer:

10 pieces of candy will cost $0.20 cents

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

Since we are given three values with one variable, and we also know that this is a ratio problem. Then we can use the Rule of Three technique to solve this problem. This technique as shown in the picture below can help us find the cost of 10 pieces of candy in a simple way.

1000 pieces   ⇒   $20

    10 pieces   ⇒   x

$\frac{10*20}{1000} = x$

$0.20 = x$

Finally, we can see that 10 pieces of candy will cost $0.20 cents
