Question

Madame Dubois bought 20 pearl neckles for $500. Becoming bored quickly, she sold 3/4 of them $40 each.She sold the rest at cost price. How much did she make

Answer 1

Answer: She made a total of $ 6100 ( I am not Sure tho .... )

Step-by-step explanation:

Total necklace = 20

Cp of 20 necklace = $ 500

Cp of 1 necklace = 500\20 = $ 20.

Sold 3/4 necklaces from total 20,

So, 3/4 = 20, ( 20/4 = 5) = 3 x 5 = 15 necklaces.

Sold at 40 each. So,

15 x 40 = $ 6000 - 1

And she sold the other at Cp ( Found above )

Rest necklace = 20 - 15 = 5

Cp of 1 necklace = 20 $

Cp 5 necklaces = 20 x 5 = $ 100 - 2

From 1 and 2 above,

Grand total = 6000 + 100 $

= $ 6100.

So, Madame Dubois made $ 6100 in total.
