In order to answer this question, you need to know how many hours
there are in one day. After that, it's a piece-o-cake.
1 day = 24 hours .
Now you can make a table:
1 day = 24 hours
2 days = 48 hours
3 days = 72 hours
4 days = 96 hours
5 days = 120 hours
6 days = 144 hours
7 days = 168 hours
8 days = 192 hours
9 days = 216 hours
10 days = 240 hours
Left:
180-53 = (8x-9)
127+9 = 8x
136 = 8x
x = 17
Right:
(15x+29) = (26x-4)
29+4 = 26x-15x
33 = 11x
x = 3
Answer:
it will cost $42 for 28
