Marsha Green makes $6.19 an hour. Find her social security tax at the rate of 7.65% for her 40 hour work week. (Work shown would be greatly appreciated)

OpenStudy (anonymous):

ok she makes $6.19 and hour and she works 40 hours a week. so we mulitply those numbers... what do you get? (btw there is still more to the problem)

OpenStudy (anonymous):

247.60

OpenStudy (anonymous):

correct. $6.19 * 40 = 247.6 ok, now we need to turn 7.65% into a number that is not a percentage. so, 7.65% is the same as 0.0765 to find out what 7.65% of $247.6 is we need to muliply: 0.0765 * 247.6 = ? what does that equal?

OpenStudy (anonymous):

18.9414

OpenStudy (anonymous):

ok now round that to the nearest tenth since it is in dollars.

OpenStudy (anonymous):

i mean hundreth

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (anonymous):
