Answer:
The question has a mistake
Step-by-step explanation:
11d+7c= 172.5
10d+7c= 155.8
By subtraction;
1d+ 0c = 16.7
1d = 16.7
11×16.7+7c=172.5
7c = 172.5-11*16.7
You will get a negative answer yet the cost cannot be negative.
< UTY + <RWX = 180°
( same side interior angle theorem ) → < UTY + <RWX = 180°
417.5
I hope this helps
