[tex] \frac{7.5}{0.45} = \frac{30}{x} \\ x = 30(0.45) \div 7 \\ x = 1.8 = 180\%[/tex]
in case there was a typo and you meant 45 dollars, then the answer is 180 dollars

if my pay is 45 USD for 7.5 hours of work

than for 30 hours = 30/7.5 = we get 4 time pay

we multiply this 4 time with 45 USD

we get 4 X 45 = 180 USD

which is also 45% of total amount.
