There are 29 known students that have dimes. Other students were asked if they had dimes but we're not recorded. It is known that 12.5% of the students had one dime.
Find the total number of students.

232 students

Step-by-step explanation:

Let the total number of students be X

Known students that have dimes =29.

Percentage of class that has one dime =12.5%

Therefore, 12.5% of X = 29

So, 12.5/100 × X = 29

0.125 × X = 29

X = 29 × 0.125 = 232 students
