There will be 1.078x students next year and equation is number of students in next year = x + 7.8% of x
<h3><u>Solution:</u></h3>
Given, There are "x" number of students at helms.
The number of students increases by 7.8% each year which means if there "x" number of students in present year, then the number of students in next year will be x + 7.8% of x
Number of students in next year = number of students in present year + increased number of students.
![\begin{array}{l}{\text { Number of students in next year }=x+7.8 \% \text { of } x} \\\\ {\text { Number of students in next year }=x\left(1+\frac{7.8}{100}\right)} \\\\ {\text { Number of students in next year }=x(1+0.078)=1.078 x}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B%5Ctext%20%7B%20Number%20of%20students%20in%20next%20year%20%7D%3Dx%2B7.8%20%5C%25%20%5Ctext%20%7B%20of%20%7D%20x%7D%20%5C%5C%5C%5C%20%7B%5Ctext%20%7B%20Number%20of%20students%20in%20next%20year%20%7D%3Dx%5Cleft%281%2B%5Cfrac%7B7.8%7D%7B100%7D%5Cright%29%7D%20%5C%5C%5C%5C%20%7B%5Ctext%20%7B%20Number%20of%20students%20in%20next%20year%20%7D%3Dx%281%2B0.078%29%3D1.078%20x%7D%5Cend%7Barray%7D)
