Rzqust [24]

Answer:

The Social Security Administration increased the taxable wage base from $106,800 to $110,100.

A:

The percent increase in the base =

\frac{110100-106800}{106800}\times100=3.09%

B:

Previous year tax = 0.062\times106800=6621.60 dollars

This year tax = 0.062\times110100=6826.20 dollars

Increase in tax = 6826.20-6621.60=204.60 dollars

Hence, Joe’s increase in Social Security tax for the new year is $204.60.

Step-by-step explanation:

GIVEN: A club is considering changing its laws. In an initial straw vote on the issue, 24 of the 40 members of the club favored the change and 16 did not. A committee of six is to be chosen from the 40 club members to devote further study to the issue.

Total members to be chosen =6

To select committee of 6 members from 40 =^{40}C_6

                                                                       =\frac{40!}{34!6!}

                                                                      =38,38,380

Hence 38,38,380 different committee can be formed.
