If Ramon wants to make 14 necklaces, how many large shells and how many small shells will he need?

Question

Ramon uses 20 shells to make one necklace. Twenty-five percent of the shella are large shells and the rest are small shells. If Ramon wants to make 14 necklaces, how many large shells and how many small shells will he need?

 

Answer 1

First, we need to know how many of each type of shell he needs to make one necklace.

 

20 shells * .25 big shells = 5 big shells per necklace

20 shells - 5 big shells per necklace = 15 small shells per necklace

 

Then, we multiply each number by 14, to find out how many of each type of shell he'll need for 14 necklaces.

 

5 big shells * 14 necklaces = 70 big shells

15 small shells * 14 necklaces = 210 small shells

 

So, Ramon will need 70 big shells and 210 small shells to make 14 necklaces.
