Martha earned a gross pay of $1,215.60 last week. Using the fact that Social Security tax is 6.2% of gross pay, determine the am
zhuklara [117]

Answer:

c. $75.37

Step-by-step explanation:

Gross pay of Martha = $ 1,215.60

Percentage of Social Security Tax = 6.2%

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.

The boat sailed 30min upstream and sailed 60km, and returned the same distance downstream (60km) and sailed it in 20min. Find th
elena55 [62]

Answer:

Step-by-step explanation:

b and c are the speeds of the boat and current, respectively.

Traveling upstream, the boat moves b-c km per hour.

Traveling downstream, the boat moves b+c km per hour.

b-c = (60 km)/(½ h) = (120 km)/h

b+c = (60 km)/(⅓ h) = (180 km)/h

Adding the equations together,

2b = (300 km)/h

b = (150 km)/h

c = (30 km)/h
