Answer:
Interest Chaney earns after 3 years is  $56.85
Step-by-step explanation:
Given:
Amount deposited = $1435.73
Simple annual interest rate = 1.32% = 1.32/ 100 = 0.0132
To find: Interest after 3 years
We know that the formula to calculate the interest amount is 
Simple interest (S.I.) = 
where, 
P is the initial amount deposited
r is the rate of simple interest in percentage
t is the time in years for which interest is to be calculated
Substituting the known values in the formula, we get
S.I = 
     = 56.85
Hence the interest Chaney earns after 3 years is  $56.85

Remark
The thing you must not do is write 7.182 as your answer. That is the exact answer found using a calculator. 
What to do.
What you should do is multiply two rounded numbers together.
7.6 rounded is 8 roughly
0.945 is almost 1. 
Your answer is 8*1 = 8 roughly. This skill is very handy when you are writing a test and you want to see if you've done the question correctly. It is easy to misplace a decimal or put in incorrect digits and this is a quick check on things like that.
