alan and scott own a sum of money.alan owns 90%.if he gives $16 to scott,he will own 85% of the money.how much money do they own
set x as the money they have
then alan owns 90%x
90%x-85%x=16
5%x=16
x=320
then own $320
x*0.9-16=x*0.85
x=320$
从题目意思要看出16美元是占总数的5%,可列式如下：
总数16/(90%-85%)=320$
Alan拥有90%*320=288$
Scott拥有320-288=32$
16÷（90%-85%）=320
alan:320×90%=288
scott:320×10%=32
设they own x money
x（90%-85%）=16
x=16/0.05=320
