Tom wants to save at least $2000. He already got $375. Let x be the amount he still needs to save.
375 + x >= 2000
Subtract 375 from both sides
375 + x - 375 >= 2000 - 375
x >= 1625
So he still needs to save at least $1625.
Hope this helps! :)
There's no way to do that without seeing the drawing or hearing a lot more information. For one thing, we don't even know the size of the circle yet.
