Kathy's retirement savings: 1188000

Mark's retirement savings: 297000

Step-by-step explanation:

Let

k   is Kathy's retirement savings

m is Mark's retirement savings

Since kathy saved four times higher than Mark, hence we have

k = 4m ...............(1)

Total savings  of both equals to $1,485,000 so we have

k+ m = 1485000 ....................(2)

substituing  k = 4m in equation (2)  

4m + m = 1485000

5m = 1485000

m = 297000

Hence

k = 4m =

k =1188000
