Alison went to an arcade where she wins 50 points per round for 8 rounds. however during the last round she gets penalized and ends with a score of -175.by how much did her score change on the last round

You start by doing 50•8= 400 because every 1 round equals 50 pts so every 8 rounds equals 400 pts. you can write a ratio if you want to. then you subtract 175 from 400 (400-175) or you can do -175+400, either way you will get 225 points in the end.

Iwould say 48 bc the line of x is the line of 6 so 6×6=48
