It is a multiplication question, just multiply: 3 x 3/4 = 9/4, now convert into mixed number and the answer is 2 1/4. I highly suggest learning how to solve simple math like this, it is quite easy.
If it’s just 40 in total for the whole session , $40 + (30 x (number of students) = ? But if it’s 40 per student as well then (40 x 30) x (number of students) = ?
