Heather bought enough shells to make x necklace each necklace holds 16 shells heather has made 10 necklaces is 16x+10 a reasonable way to represent the number of shells that heather has left to make necklaces with explain your answer

Hello!

the information that we have is:

Heather bought enough shells to make x necklace.

Each necklace needs 16 shells.

Heather has made 10 necklaces.

If heater bought enough shells to make x necklaces, and she already did make 10 necklaces, then she can make another (x - 10) necklaces.

this (x - 10) necklaces need 16 shells each, then she has a total of:

(x -10)*16 shells left.

then the given equation "16x+10" is not a reasonable way to represent the number of shells that Heather has left to make necklaces.
