Kay spends 250 minutes per week exercising. Her ratio of aerobics to weight training is 7 to 5. How many minutes per week does she spend on aerobics? How many minutes per week does she spend on weight training?
------------
aero/weight = 7/5 = 7x/5x
--------
EQUATION:
7x+5x=250
12x=250
x=20.833333
aerobics time = 7x = 7(20.8333333...) = 145.83333... minutes
