Correct Answer:
<em>To maximize their profit, Esibu must build 6 (2 grandmother clock and 4 wall clock) while Dela must build 8 (6 grandmother clock and 2 wall clock).</em>
Step-by-step explanation:
Since they don't want to work for more than 20 hrs in a week
In-order to maximize the profit,
For Esibu,
2 grandmother clock = 4 hours ×2 = 8 hours
4 wall clock = 3 hours × 4 = 12 hours
Total hours = 20 hours.
For Dela,
6 grandmother clock = 2 hours × 6 = 12 hours
2 wall clock = 4 hours × 2 = 8 hours
Total hours = 20 hours.
Yang tidak hadir = 12
yang hadir = 40 - 12 = 28 orang
perbandingan = 28 : 40
dibagi dengan 4
7 : 10
jadi perbandingannya 7 : 10 atau 7/10
