Answer:
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
