How do i get the revised bill rate ?

The initial pay rate is $16.00. It is also mentioned that the price is marked up by 78.7%. It means that the prices are increased by 78.7%. Also, there is a profit of 10% too. So, the pay rates after mark up will be

$16.00 + (78.7% of 16.00)

= $16.00 + $12.592

=$28.592

And the pay rates after estimated profit is

$28.592 + (10% of $28.592)

= $28.592 + $2.8592

= $31.4512

Hence, the revised bill rate, rounded to the nearest cent is $31.45.
