Within this question, the listed tests have been put in the order of how
rigorous they are. Whilst a PAR-Q test simply involves the test
participant writing down the answers to a series of question, the other
tests included in the question all need a doctor present in order to be
performed. For example, the most rigorous test, the exercise stress
test, is only ever used when it is suspected that a patient might have a
condition that could be fatal.
If she deposits $1200 and it earns an interest of $144 over 2 years, then she earns $72 per year. Meaning that after 7 years her account will have a balance of $1704
$1344 - $1200 = 144
144/2 = 72
72 * 7 = 504
$1200 + $504 = $1704
