Answer:
THE TOTAL INTEREST EARNED = $ 385
Step-by-step explanation:
Interest earned by sal from first account can be calculated as follows :
Principal value (P) = $1000 .
interest rate (R) = 7.5 % .
Time period (T) = 1 year .
= $ 75 .
SIMILARLY , we can find the intrest earned by rest amount.
Principal value (P) = $5000 - $ 1000 = $ 4000 .
Interest rate (R) = 7.75 % .
Time period (T) = 1 year .
= $ 310 .
THE TOTAL INTEREST EARNED = $ 75 + $ 310
= $ 385
