Problema Solution
Heather bought enough shells to make "x" necklaces. Each necklace holds 16 shells. Heather has made 10 necklaces. How many shells does heather have left?
Answer provided by our tutors
Since Heather can make 'x' necklaces the total number of shells she has is 16x.
She made 10 necklaces and user 10^16 = 160 shells.
We subtract the number of used shells from the total number of shells to find out how many shells are left:
16x - 160 shells are left.
