Question

Emma’s Extreme Sports hires hang-gliding instructors and pays them a fee of $\backslash (50$ per class as well as $\backslash )20$ per student in the class. The total cost Emma pays depends on the number of students in a class. Find the equation that expresses the total cost in terms of the number of students in a class.

Short answer

The equation that expresses the total cost in terms of the number of students in a class is$y=50+20x$.

Step-by-step solution

Given Information

Consider that hang-gliding instructors are hired by Emma's ES.

Let,$y=$Total cost Emma pays.

$x=$Number of students in a class.

Explanation

To find the equation that expresses the total cost in terms of the number of students in a class:

A fee of $\$50$is the fixed cost of hiring hang-gliding instructors. If there are $x$number of students in a class, then $(20\times x)$is the cost or fee of hiring hang-gliding instructors. Hence, the equation that expresses the total cost in terms of the number of students in a class is written below:

$y=\$50+(\$20\times x)$.
