Problema Solution
A mechanic has a radiator hose that measures 32 feet long, which needs to be cut into 5 feet 3 inches long pieces. What is the most number of pieces that can be cut?
Answer provided by our tutors
1 ft = 12 in
1 in = (1/12) ft
3 in = 3/12 ft
3 in = 1/4 ft
Let 'x' represent the number of pieces, x>0 and x is integer.
Now we can write:
(5 + 1/4)x <= 32

........
x <= 6.1
Since 6 is the largest integer number smaller than 6.1 the most number of pieces that can be cut is 6.
