Analyze the simplification to each of the following algebraic expressions:
w + 3(y + 8w) = 3y + 11w
9(p β 4) β 3(8p + 5) = -15p + 1
7 β 5y(3 + w) = 7 β 15y + w
Explain the common error pattern. Support your explanation by including the correct simplification for each expression.

Someone answer asap for ! a discount storeβs 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)) =
