Answer:
2257m3
Step-by-step explanation:
50x25x2=2500
2500-243=2257
X=11
-5(x+1) = -3(2x-2)
distribute
-5x-5= -6x+6
both +6x
x-5=6
plus 5 on both
x=11
You should use part/whole = %/100 and cross multiply. So you will get 20/x = 80/100 (whole is x because we are trying to find what whole is). now you will have 2000=80x. Now you divide 2000/80 and get 25=x. So, there are 25 costumes in total which means they need to make 5 more.
