The number of each type of book is what is unknown, so we can represent those quantities with variables. Let x = the number of hardbacks and y = the number of paperbacks. Then we know that: x + y = 65 (the total number of books sold) We also know the total cost of both editions, which is $1356. It can be written algebraically as: 28x + 12y = 1356 We now have a system of two equations, which can be solved by substitution. It would be easier to solve the first equation for either x or y and substitute that into the second equation.

In the market for personal computers, we would expect the Equilibrium quantity to rise and the change in the equilibrium price to be ambiguous.

<h3>What is equilibrium quantity?</h3>
  • When there is no shortage or surplus of a product on the market, it is said to be in equilibrium quantity.
  • When supply and demand meet, the amount of an item that consumers want to buy equals the amount supplied by its producers.
  • The equilibrium price is the only price at which consumers' and producers' plans coincide—that is, the amount consumers want to buy of the product, quantity demanded, equals the amount producers want to sell, quantity supplied.
  • Assume there is an increase in both supply and demand for personal computers.
  • The Equilibrium quantity would then rise in the market for personal computers, while the change in the equilibrium price would be ambiguous.

Therefore, in the market for personal computers, we would expect the equilibrium quantity to rise and the change in the equilibrium price to be ambiguous.

Sever21 [200]

 The ability to automatically detect the occurrence of an abnormality, thereby helping achieve quality at the source, is jidoka

Therefore, Jidoka's definition is best understood as "automation". This means manual automation or autonomous automation. The origin of Jidoka can be traced back to Toyota Motor Corporation, which was founded by Sakichi Toyoda as a textile manufacturer.

A famous example of Jidoka is his Model G for Toyoda Automatic Loom, invented and patented in 1925 by Sakichi Toyoda (1867–1930). This is one of the many looms invented by this inventor, but perhaps his most famous. This loom could be operated almost unmanned. Jul 31, 2018

Automation is a commonly used term in Lean Manufacturing, widely considered one of the pillars of the Toyota Production System, the other being Just in Time (JIT). The term "Jidoka" is often used to impress others, but the idea behind it is less common outside of Toyota.

neonofarm [45]

Answer: Floating exchange rate                

             

Explanation: The floating exchange rate is a mechanism under which a country's exchange prices are set by the supply and demand-based foreign exchange market compared to other currencies. It compares with a fixed exchange rate, wherein the government decides the rate completely or mainly.

Floating currency regimes mean that lengthy-term currency price movements represent relative economic power and country-to-country rate of interest differences.

A currency that is too high or low may have a negative impact on the country's economy, impacting trade and debt-paying efficiency. The state or banking system would try to take action to bring their currencies towards a more desirable level.
