Answer:
APR = 416%
EAR = 5370.60%
Step-by-step explanation:
Given:
Interest rate = 7.8% per week
Now,
In an year there are total 52 weeks
thus,
The APR (Annual percentage rate) = Interest rate × Total weeks in an year
or
APR = 8% × 52
or
APR = 416%
and, EAR ( Effective Annual Rate ) = ( 1 + r )ⁿ - 1
Here,
r is the interest rate per week
n is the total weeks in an year
thus,
EAR ( Effective Annual Rate ) = ( 1 + 8% )⁵² - 1
= ( 1 + 0.08 )⁵² - 1
= 53.7060
or
53.7060 × 100% = 5370.60%
Using proportions, it is found that Sharifah owns $8,330 in taxes.
<h3>What is a proportion?</h3>
- A proportion is a <u>fraction of total amount</u>, and the measures are related using a rule of three.
- Hence, using proportions, a percentage x% of an amount a is given by:
.
<h3>Taxes for the first $34,000:</h3>

<h3>Taxes for the amount above $34,000:</h3>
- The amount taxed is $27,000, as 61000 - 34000 = 27000.

Then, the total amount is:

Sharifah owns $8,330 in taxes.

Answer:
1/3
Step-by-step explanation:
Number cube has 6 sides so a number greater than 4 is 5 and 6. Which is 2 times so 2/6 which can simplify to 1/3
