Firstly we need to count how much did the employees earn after the raises:
4% from $41,000 =
= 4/100 * 41,000 =
= 4 * 410 =
= 1644
4,5% from 43,700 =
= 45/1000 * 43,700 =
= 45 * 43,7 =
= 1966,5
3% from 39,700 =
= 3/100 * 39,700 =
= 3 * 397 =
= 1191
Now we need to sum up all the raises:
1644 + 1966,5 + 1191 = 4801,5
So now we can clearly see that answer A ($4,802) is the closest one to the total of all three raises.
