Tolong dijawab kak.hari ini dikumpulkan.pakai langkah-langkahnya.plis kak
A + B = 500
A = 500 – B
2.500A + 1.250B = 1.000.000
2A + B = 800
2(500 – B) + B = 800
1000 – 2B + B = 800
-2B + B = 800 – 1000
-B = -200
B = 200
A = 500 – B
A = 500 – 200
A = 300
Keuntungan
= 250A + 100B
= 250(300) + 100(200)
= 75.000 + 20.000
= 95.000
Jawaban C
