100% of 62 = 100% * 62 = 1 * 62 = 62
62 percent of 55200 .62 * 55200 34224
To find 62 percent of a number, multiply the number by 0.62. In this instance, 0.62 x 62 = 38.44. Therefore, 62 percent of 62 is equal to 38.44.
This information tells us that (248/x) = (62/100) , by the definition of percentage. Thus x = 248*(100/62) = 400 so there are 400 students in the class.

To find out how much of the 30% acid solution is needed, we can set up a weighted average equation. Let x be the volume of the 30% solution needed. Since the final solution is 62% acid, we can write the equation as: 0.80*(400-x) + 0.30x = 0.62*400. Solving this equation, we find x to be 280 liters. Therefore, 280 liters of the 30% acid solution is needed to make a 400L solution that is 62% acid.
