For this, we are going to want to take $20 and divide it by 4 to get the amount of work done in one hour. From 20 divided by 4 we get $5. From here, we need to see how much is made in 200 hours. Therefore, we multiply 200 times 5 and we see that you will make $1000.
The answer is $1000. I hope this helps, have a great day, and God bless! Brainliest is always appreciated :)
