Step-by-step explanation:
The interest is computed using the formula ...
I = Prt
where r is the annual rate, and t is the time in years. Banks compute interest using "ordinary interest", which assumes a 360-day year. Trevor's interest is ...
I = $241(0.0194)(54/360) = $0.70
Answer:

Step-by-step explanation:
You need to know this indice rule:
If you multiply two terms with the same base, then add their powers and multiply their coefficients.
: Here we have to multiply each term in the first pair of brackets by the term in the second pair of brackets.
So we can split this into parts:

Now using the rule above expand the brackets:
: Notice how
since
so
.
: Be careful with negatives, two negatives make a positive.
Now add them all together:
