every month, Mr Lopez spends 60 percent of what he earns and saves the rest. Mr Lopez earns n dollars and saves r dollars each month.

express r in terms of n​

we have that

r=(1-0.60)n

r=0.40n

because

each month Mr Lopez spend 0.60n

that means

the remaining is (1-0.60)n=0.40n

therefore

r=0.40n
