10 pairs of earrings and 5 necklaces (the maximum profit will be $250)

Step-by-step explanation:

Let x be the number of earrings and y be the number of necklaces Lisa makes.

1.  Lisa only has enough materials to make 15 total jewelry items per week, then

2.  It takes half an hour to make a pair of earrings, so it takes her hours to make x earrings. It takes her 1 hour to make a necklace, so it takes her y hours to make y necklaces. Lisa only has 10 hours a week to make jewelry, thus

3. Lisa makes a profit of $15 on each pair of earrings and $20 on each necklace. In total her profit is

You have to find the maximum value of the function with respect to inequalities
