In planning her​ retirement, Liza deposits some money at 2.5​% ​interest, with twice as much deposited at 3.5​%. Find the amount deposited at each rate if the total annual interest income is ​$1235

Answer 1

x = amt @ 2.5%

2x = amt @ 3.5%

.025x + .035(2x) = 1235

Solve for x and then calc 2x to obtain the respective deposit amounts.

Check by applying the interest rates to their respective deposits to see if total interest checks out @ $1,235.
