$180

Step-by-step explanation:

If in 7.5 hours you get $45 then add 7.5 and 7.5 to get 15 hours.

Now 15 + 15= 30 so because of that you can know that 7.5 times 4 gives you your 30 hours.

So now all you have to do is do 45 times 4 to get your end result of $180.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24
