Answer:

$150

Explanation:

Equilibrium price occurs at the point when the supply and demand of the product equals.

For example: Quantity of pens demanded in the market is 250, and Quantity supplied in the market is 250 as well.

With the same logic we can conclude that: At $150 the demand and supply of music players equals hence, it is the equilibrium price.

Please help me with 13 and 15 asap

Law Incorporation [45]

Gosh, I've done this problem before. Let's start with 13. In this problem, we're basically just skip counting. For example, in the roses row, in the second bouquet, we know we have to add 4 more flowers, so we can document 8. Continue to skip count for both. For 15, we would have about 96 more movie posters remaining, making our ratio 96:x. So, 96:x = 120:100. Therefore, x would equal 80- as 96:80 equals 120:100. If she needs 80 and already had 100, she should sell 20 posters. Hope this helped.
