Answer:
594.1
Step-by-step explanation:
87÷15=5.1
672-83=589
so then you add those to together and get 594.1
The answer to the question
Estimate 189 to the nearest tenth which would be 190. And then do the same for 643 which would be 640. 640-190= 450
I believe your answer is C, because Y (payment after taxes) is x (what he recieved the first time) minus taxes (0.18%) Hope this helped!
