How do you set- up and equation for this word problem?
Kay spends 250 min/wk exercising. Her ratio of time spent on aerobics to time spent on weight training is 3 to 2. how many minutes per week doe she spend on aerobics? How many minutes per week does she spend on weight training?
**
let x time spent on weight training
250-x=time spent on aerobics
x/(250-x)=3/2
2x=750-3x
5x=750
x=150 x
250-x=100
ans:
min/wk spent on weight training=150
min/wk spent on aerobics=100
