Question

Ms. Webb said that 50% of her students made a B, 20% made a C and the rest of her students made an A last six-weeks. If 33 students made an A_(, ) how many total students does MS. Nebb have?

Answer 1

Ms. Webb has a total of 110 students in her class.

Step-by-step explanation:

To find the total number of students in Ms. Webb's class, we need to first determine the percentage of students who made an A. Since 50% made a B and 20% made a C, the remaining percentage that made an A can be found by subtracting the sum of 50% and 20% from 100%. So, the percentage of students who made an A is 100% - 50% - 20% = 30%.

If 33 students made an A, we can set up a proportion to find the total number of students. Let x be the total number of students. We can write the proportion as: 30% (A students) = 33 / x. Next, we can convert the percentage to a decimal by dividing it by 100, so 30% becomes 0.30. Now we can solve for x by cross-multiplying: 0.30x = 33. Divide both sides by 0.30 to isolate x: x = 33 / 0.30. Using a calculator, we find x is approximately 110. Therefore, Ms. Webb has a total of 110 students in her class.
