Problem $638603$:

Do not include anything other than numbers in your responses. For example, do not include comma or dollar sign in your numbers. As a rule of thumb, keep $2$ decimal places for larger numbers and $3$ decimal places for smaller numbers less than $1.$

Samsung manufactures cellular phones at a processing cost of $$205$ per unit. Currently, the company produces an average of $2009$ phones per day, $83$ percent of which are good$-$quality phones, resulting in $17$ percent defective phones, $67$ percent of which can be reworked. The cost of reworking a defective phone is $$71.$

They also consider a quality improvement initiative: They can replace a plastic component with a metal one which increases the initial cost of processing phone to $$210,$ but the percentage of defective items decreases to $12$ percent. With this quality improvement option, nothing else would be different from the current situation $($for example the cost of rework and the percentage of defectives that can be reworked stay the same$).$

Calculate the followings:
