For this question, I would first see what one child is equal toby divide the children by the percentage.
15÷3= 5
Each child is worth 5%. If you know each child is worth 5%, and the total number of students are 100%, then you can divide.
100÷5= 20
There are 20 students in the class. To make sure our answer is right, we can check to see if 3 students are 15 percent.
3÷20= .15×100= 15
So yes, there are 20 students in the class.

Step-by-step explanation:
He should get it at Mikes bikes because 25% of $300 is 225. If he buys it at cycle center he will pay $275 for his bike and get $40 off of his next bike after he purchases his first bike. Mikes bikes is cheaper. Plus he wouldn't need another bike for another couple years.
You should find the interest (29% equals to 29/100)
29% X1700=493
So you have to pay $493 on top of $1700
total : 1700+493=2193
