1. there were 136 students and 34 adults in the concert. if 85% of the seats were filled how many seats are in the auditorium?
2. 40% = 32/x

1. 136+34= 170 total concertgoers. If we divide 170 by 85, we get 2; so each percentage point equals 2. Multiply 2 by a hundred and you get 200 people in total
 
2. Is this question to solve for X? in that case, we can solve it easier in the form 

then we try and dive them the same numerator by multiplying each by the other:

This tells us that 

so .

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

11/36 is .305 repeating
