Answer:
D) All three have the same correlation coefficient.
Total income = 11.75 x 40 x 4 = $1,880
Less: FICA = 0.0765 x 1,880 = $143.82
Federal tax = 0.1075 x 1,880 = $202.10
Stare tax = 0.075 x 1,880 = $141
Net Income = $1,393.08
1. Convert the percents to decimals (you can do this by dividing each # by 100);
8/100= .08
15/100= .15
2. First take off the 8%;
$55.35 * .08 = $4.43
3. Take off the 15% (still use the original bill amount);
$55.35 * .15 = $8.30
4. Add the $ together after find the rate for each percent.;
$4.43 + 8.30 = $12.73
5. Subtract the add rates from the bill;
$55.35 - $ 12.73 = $42.62(answer)
