Answer:
55 people.
Step-by-step explanation:
Multiply 220 by the percentage in decimal form. To make any percentage to a decimal, simply move the decimal 2 spaces to the left. Now instead of 25, you have 0.25. Multiply this by 220 to get 55. Hope the Helps!
84% of 50 is 42. So if your test was graded out of 50 you would've gotten 42/50. If you multiply 50 by 2 (50x2), you have 100, so then you'd just divide the 84% by 2 so you'd get 42%
