If my last paycheck way $107.78 and I work for 3 and a half hours a day for 5 days, how much do I make an hour?

Tresset [83]

Answer:

$6.16

Step-by-step explanation:

Total amount paid = $107.78

Total time worked = 3 and half hours for 5 days

$=3\dfrac{1}{2}\cdot 5\\ \\=\dfrac{7}{2}\cdot 5\\ \\=\dfrac{35}{2} \ hours$

Amount earned per hour

$=\$107.78:\dfrac{35}{2}\\ \\=\$107.78\cdot \dfrac{2}{35}\\ \\\approx \$6.16$

nignag [31]

Answer:

$f^{-1}$ (22) = 7

Step-by-step explanation:

The inverse function maps the output of the function back to its input

f(7) = 22 means when input is 7 the output is 22

The inverse maps the output 22 back to the input 7 , that is

$f^{-1}$ (22) = 7
