Acomputer consists of a cpu and an i/o device d connected to main memory m via a shared bus with a data bus width of one word. the cpu can execute a maximum of 106 instructions per second. an average instruction requires five processor cycles, three of which use the memory bus. a memory read or write operation uses one processor cycle. suppose that the cpu is continuously executing "background" programs that require 95% of its instruction execution rate but not any i/o instructions. assume that one processor cycle equals one bus cycle. now suppose that very large blocks of data are to be transferred between m and d.

Mauro products distributes a single product, a woven basket whose selling price is $15 and whose variable expense is $12 per unit. the company’s monthly fixed expense is $4,200. required: 1. solve for the company’s break-even point in unit sales using the equation method. 2. solve for the company’s break-even point in dollar sales using the equation method and the cm ratio. (do not round intermediate calculations. round "cm ratio percent" to nearest whole percent.) 3. solve for the company’s break-even point in unit sales using the formula method. 4. solve for the company’s break-even point in dollar sales using the formula method and the cm ratio. (do not round intermediate calculations. round "cm ratio percent" to nearest whole percent.)
