Tolong bantu jawab y,pakai cara,terserah mau jawab nomor brp aja

7) Amir : Budi = 3 : 5
Budi = 5/8 × 240.000
= 150.000

3.
X/8 = 28
X = 224

224/(8+6) = 16 hari

4.
X/21 = 60
X = 1260

10 hari kerja
X1 = 10 × 21 = 210
X2 = 1260 - 210 = 1050

1050/(21 + P) = 60 - 10 - 20
1050/(21 + P) = 30
21 + P = 35
P = 14 orang

5.
X/15 = 30
X = 450

450/(15+P) = 25
15 + P = 18
P = 3 orang
