Okay so this problem basically is saying if the value is 90000 and per every 1000 she has to pay 31$ in tax
So first divide $90,000 by $1,000 you should get 90
Now you can do 90 times $31 to find how much tax she will have to pay which equals $2,790 tax total
I think they both go into 10,000 bases of the calculations from the calculator on my phone
4 tens and 10 ones is 410
