Answer:

1193

Explanation:

If the number of students decreased to 98% of last years total, the total students decrease by:


100-98=2

The amount of students decreased by 2% from the previous years total. We can then determine the amount of students that we 2% of the current total. We first convert 2% into a fraction:


2/100=1/50

Therefore:


1170*(1/50)=234/10=23.4

So in order to get this years total we must add 23.4 to this years total:


1170+23.4=1146.6≈1193

There were 1193 students last year
