Answer:
$37.05
Step-by-step explanation:
If you take 15% and 20% you get (15%+20%) which is 35%, then you take 100%-35% you get 65%, 65% of 57 is 37.05.
Thus Your Answer: $37.05
In this problem you cross multiple. So on Monday 15 out 20 students vote which is 15/20 and the second one is 16 students present and we don’t know how many people voted which is x/16 so we multiple 20 by x and 16 by 15 we get 20x=240 we need to isolate x so we divide 20 on both sides and x=12
Answer:
19. 9000
20. 5000
21. 63000
22. 167000
23. 77000
24. 34000
25. 1000
26. 9000
27. 122000
Step-by-step explanation:
To do this, all you need to do is pay attention to the 4th digit and the third. Take 27 for example, 121,619. The fourth digit is 1, and the third digit is 6. because the third digit is 6, the fourth digit gets rounded up to 2. All numbers higher than the fourth digit (fifth, sixth, etc) stay the same and all digits below the fourth digit (first, second, third) become zero. hope this helps!
