Kinda

Answer 3

0.03x+0.035y = 155

x + y = 5000

x = 5000-y Plug it into the first one

0.03(5000-y) + 0.035y = 155
150 - 0.03y + 0.035y = 155
0.005y = 5
y = 1000 <~~Answer that was put into the 3.5% account.

Since 1000 was put into the 3.5% account, 4000 was put into the 3% account.

Answer: $4000
