Question

Nina deposits $3500 into savings account. The rate of simple interest is 5.5% p.a.

Answer 1

A) $3500*0.055 = $192.50 . . . . the interest paid each year

B) The problem makes no mention of compounding, so we assume simple interest is paid. (Most accounts do not work this way.)
.. at the end of 1 year, 3500 +192.50 = $3692.50
.. at the end of year 2, 3692.50 +192.50 = $3885.00
.. at the end of year 3, 3885.00 +192.50 = $4077.50
.. at the end of year 4, 4077.50 +192.50 = $4270.00
.. at the end of year 5, 4270.00 +192.50 = $4462.50
