Freddy’s savings account went from $520 to $321 after he purchased a new bike. What was the percent decrease?

Vinil7 [7]

Step-by-step explanation:

The bike cost $199 to get $199 you do a number line then label 520 then at the end label 321 so then you do -20 then -100 then -50 then -20 then -9. so now you add them up 20+100+50+20+9 which equals =199

so bike cost $199

then 520%×199= 1034.8

or 520%×321=1669.2

so the percentage is 1669.2 or 1034.8 probably 1669.2 but they bot count.
