After being used, a napkin can be cleaned by one of two methods: fast service or slow service. Fast service costs $0.10 per napkin, and a napkin cleaned via fast service is available for use the day after it is last used. Slow service costs $0.06 per napkin, and a napkin cleaned via slow service is available two days after they were last used. New napkins can be purchased for a cost of $0.20 per napkin.

- Question: Pistons for automotive engines can be formed either by casting or forging technique. Traditional cast pistons are considered good enough by most engine tuners and builders when it comes to standard setups. They suffer no significant drawback in terms of compression and service life. Performance enthusiasts and custom engine builders prefer the use of forged pistons because they are more durable and easily customised to any configuration, which is essential for engine tuning. Cast pistons are made with the use of large, specialised equipment made up of a mould where the molten aluminium alloy is poured to create the piston shape. Forged pistons employ a single-cast billet of the alloy which is stamped into the required shape using a die. The shape of the die determines the size and shape of the piston. The productivity rates for both methods are different. How do i calculate this?: In this Question, we assume that one unit piston weighs 1.54kg. To calculate the cost per part…arrow_forwardQuestion Consider the following transactions occurring during a given fortnight.
