Write a system of equations for the following scenario. Then solve the system using matrices. 10) Samantha is supposed to buy movie tickets for a large group of people. She was given $580 to
cover the cost of the tickets, but she doesn't remember how many of each type of ticket to buy. She
remembers that there are 74 people total going to the movie. She also remembers that the number of
adults is equal to the sum of the number of students and children. If each adult ticket costs $9, each
student ticket costs $7, and each child ticket costs $6, how many of each ticket does Samantha need
to buy? Write the original equation, the matrices you are using and the final answer with labels
for full credit!

At a sale this week, a desk is being sold for $213. this is a 29% discount from the original price. what is the original price?

Someone answer asap for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
