Answer:
[(1/12)(5/5) + (1/20)(3/3)](x hours) = 1
(5/60 + 3/60)x = 1
(8/60)x = 1 we can reduce 8/60 by dividing out a 4
(2/15)x = 1 x both sides by 15/2
x = 15/2
x = 7 1/2 or 7.5 hours
The standard form of this equation is

The slope of two parallel lines i the same, so the slope of the line we're looking for is also

Since the line passes through

, the equation is:

Increase = 14
Total =50
Percentage increase = 14/50 x 100 = 28%
