Answer:
c. $75.37
Step-by-step explanation:
Gross pay of Martha = $ 1,215.60
Percentage of Social Security Tax = 6.2%
In order to find the amount of Social Security Tax we need to find out what is 6.2% of $ 1,215.60
6.2% in decimal form will be 0.062
So,
6.2% of $ 1,215.60 = 0.062 x 1,215.60
= $ 75.37
This means, the amount of Social Security Tax is $ 75.37. Therefore, option C gives the correct answer.
Answer:
$16
Step-by-step explanation:
Simple interest is based on the principal amount of a loan or deposit, whereas compound interest is based on the principal amount and the interest that accumulates on it in every period.
Simple Interest = P x r x n
where P = Principal amount, r = Annual interest rate, n = Term of loan, in years
2% = 2 ÷ 100 = 0.02 so r = 0.02
Therefore,
Simple Interest = 400 x 0.02 x 2 = 16
So she will be paid $16 in the first two years.
You must travel at 42 mph for 4 hours
<em><u>Solution:</u></em>
Time varies inversely as rate of motion
Let "t" be the time required
Let "r" be the rate of motion
Then, we get
Where, "k" is the constant of proportionality
<em><u>You travel 3 hours at a rate of 56 mph</u></em>
Substitute t = 3 and r = 56 in eqn 1
<em><u>Find the rate you must travel for 4 hours</u></em>
r = ? and t = 4
Substitute t = 4 and k = 168 in eqn 1
Thus you must travel at 42 mph for 4 hours
