Answer:
isabel saves the most of their salary each month
Step-by-step explanation:
Let say Salary of Gavin , Harry & Isabel = 100S
Gavin saves 28%
=> Gavin Saving = (28/100)100S = 28S
harry spends 3/4 of his salary
=> Harry Spends = (3/4)100S = 75S
Harry Saving = 100S - 75S = 25S
the amount of salary isabel saves: the amount of salary she spends 3:7
the amount of salary isabel saves = 3k
the amount of salary isabel spends = 7k
3k + 7k = 10k = 100S
=> k = 10S
the amount of salary isabel saves = 3k = 3 * 10S = 30S
30S > 28S > 25S
isabel Saving > Gavin Savings > Harry Savings
isabel saves the most of their salary each month
