Course Enrollment Use this pictograph to answer exercises 1–-4.
How many students are enrolled in prealgebra?
To calculate: The number of students joined the prealgebra course from the provided pictograph.
Answer to Problem 1RP
Solution:
The number of students who are a part of the prealgebra course is 350.
Explanation of Solution
Given Information:
A pictograph showing the number of units enrolled for three courses, namely, prealgebra, algebra and calculus and the value of each unit is 50 students.
Formula Used:
If a variable consists of n number of units and the value of each unit is m, then the value of the variable is as follows:
Calculation:
From the graph, it can be clearly seen that the number of units who have joined prealgebra discipline is 7 units.
Since, one unit consists of 50 students, therefore, the total number of students who are a part of the prealgebra course is:
Thus, 350 students are attending prealgebra course.
