In a certain school 70% of the students in first-year chemistry have had algebra. If there are 290 students in first-year chemis
KiRa [710]

The number of the students in the school that have had algebra is 203

<h3>How to determine the number of students?</h3>

The given parameters in the question are

  • Proportion of students taking algebra, p = 70%
  • Number of students in the school, n = 290

The number of students that had algebra in the school is calculated as:

Algebra = Proportion of students taking algebra * Number of students in the school

The above equation can be represented as:

Algebra = np

Substitute values for n and p in the above equation

So, we have

Algebra = 290 * 70%

Express 70% as decimal i.e. 0.70

So, we have

Algebra = 290 * 0.70

Evaluate the product i.e. multiply 290 and 0.70

So, we have

Algebra = 203

Hence, the number of the students in the school that have had algebra is 203
