An electronics store has a current inventory of 50 stereo systems. The lowest priced stereo system in the store sells for $800, The lowest priced stereo system in the store sells for 800 dollars, and the highest priced stereo system sells for $3000. and the highest priced stereo system sells for 3000 dollars. Which of the following is the maximum amount of $3000 systems on hand Which of the following is the maximum amount of 3000 dollar systems on hand if the current inventory totals $111,000

B) 32  

Explanation:

let H = number of expensive high price stereo systems

let L = number of less expensive low price stereo systems

H + L = 50

3,000H + 800L = 110,000

H = 50 - L  (now replace)

3,000 (50 - L) + 800L = 110,000

150,000 - 3,000L + 800L = 110,000

150,000 - 110,000 = 3,000L - 800L

40,000 = 2,200L

L = 40,000 / 2,200 = 18.18 ≈ 18 lower priced stereo systems

H = 50 - 18 = 32 higher priced stereo systems

(3,000 x 32) + (800 x 18) = 96,000 + 14,400 = 110,400

Even though the answer is not exact, if you had 33 high cost stereo systems, your inventory's cost = $112,600 which is $1,600 off

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'

answer; rapid growth in buyer demand and high buyer switching cost;
