CPM Homework Help : ACC7 Problem 7-24

Copy the diagram below on your paper. Use the given information to fill in all of the missing labels.

A line segment, labeled on the ends, top & bottom, left: 0 & 0%, right: question mark & 100%. Divided int 2 unequal sections, each bracketed and labeled as follows: Left: top, question mark students, bottom, 60%. Right: top, 28 students, bottom question mark %.

Hint 1:

First, solve for the lower half of the diagram.

Answer 1:

Label added to bottom right bracket, 40%. Since the entire diagram is representative of $100\%$ of the students, and the first portion represents $60\%$ , the second portion must represent $40\%$ .

Hint 2:

$28$ students is $40\%$ of how many total students?

Answer 2:

$\frac{40}{100}=\frac{28}{x}$ Label added to top right end, 70 students.

More Help:

To find the remaining number of students for the first portion, subtract $28$ from the total number of students.
