Hey!!!!
________
let the age of Marissa be x years and Regan be y years.
Then ATQ,
=> x + 10 = y -----(1)
Also,
After 10 years
=> 80% of y = x
=> 80y/100 = x
=> 4y = 5x
Using (1) in above equation
=> 4(x + 10) = 5x
=> 4x + 40 = 5x
=> x = 40
Thus y = 50.
Thus Marissa is 40 years old and Regan is 50 years old.
