If i could get on any of these answers tell me im really struggling

I believe that number 1 is 12 because it says that they played 15 games but they were defeated in 3 which is simple subtraction.. 15-3=12

For #1 I would do 3+w=15 and subtract 3 on both sides and then
3+w=15
-3 -3
— —
w=12
They won 12 games
#2 I would do 27 times 3 because if they each payed 27 dollars and they split the bill so do 27•3 witch is 81 the bill was $81

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425

Where’s the stuff st? ? lol sorry
