The Original Cookie Factory bakes and sells four types of cookies: chocolate chip, sugar, molasses, and peanut butter. Matrix A indicates the number ofunits of various ingredients used in baking a dozen of each type of cookie. The cost, in cents per cup or per egg, for each ingredient when purchased insmall quantities and in large quantities is indicated in matrix B.

A newspaper surveyed companies on the annual amount of money spent on television commercials and the estimated number of people who remember seeing those commercials each week. A soft-drink manufacturer spends $40.1 million a year and estimates 78.6 million people remember the commercials. For a package- delivery service, the budget is $22.9 million for 21.9 million people. A telecommunications company reaches 88.9 million people by spending a whopping $154.9 million. Which matrix below DOES NOT represent this situation? (All value in millions) 40.1 22.9 154.9 C = 78.6 21.9 88.9 21.9 22.9] C = 78.6 40.1 59°F Cloudy 一一

This is one question, I couldn’t fit it into one picture so I insert 2.
Felipe, Pablo, and Amy each sell avocados for $1.40 each, boxes of strawberries for $1.90 each, and tomatoes for $0.70 each. They don't sell any other food. The number sold by each seller and each type of food is as follows. Felipe Pablo Amy Number sold Avocados Boxes of strawberries Tomatoes 400 440 620 570 530 520 The table can be represented as the following matrix. 400 420 440 A 620 590 570 530 480 520 420 590 480 (a) Find a matrix B whose entries are the prices (in dollars) of each type of food. Make sure the product AB is defined and its entries are the amounts of money (in dollars) made by each seller overall. B = 0 (b) Calculate the product AB. AB= 0 (c) How much money (in dollars) did Felipe make overall? $0 믐 1000 000 X 00 [000) Undefined
I believe A is correct, but I am not sure about w. It needs to be written as a fraction. Thanks!
The figure to the right shows the letter L in a rectangular coordinate system. The figure can be represented by the matrix B, shown to the right. Each column in the matrix describes a point on the letter. The order of the columns shows the direction in which a pencil must move to draw the letter. The L is completed by connecting the last point in the matrix, (0,9), to the starting point, (0,0). Use these ideas to complete parts (a) and (b) below. a. If A = AB - 1 0 [!!] 0 1 find AB. (Simplify your answer.) b. Graph the object represented by matrix AB. What effect does the matrix multiplication have on the letter L represented by matrix B? Choose the correct graph below. A. O B. Rotates the letter L about the origin. Reflects the letter L across the x-axis. O C. Q 077 11 0 B-[07718] 001 199 B= Reflects the letter L across the y-axis.
Two departments of a firm, A and B, need differing amounts of steel, wood, and plastic. The table on the right gives the amount of each product the departments need. These three products are supplied by two suppliers, Company C and Company D, with the unit prices given in the table on the right. C a. Use matrix multiplication to determine how much these orders will cost each department at each of the two suppliers. Enter the amounts into the cost matrix shown on the right. Dept. A Dept. B Department A Department B Steel Wood Plastic Co. C Company C 580 280 280 Co. D Company D — 570 180 380 Steel 70 60 Wood 60 40 Plastic 40 60
