-----------------
Let # with a drivers license last year be "x".
x + 0.24x = 558
1.24x = 558
x = 450

students at westwood high school with a drivers license = 558.
this is 24% more than last year.
No of students who had a drivers license last year = N
No of students who had a drivers license this year = 1.24xN
1.24N=558
N=558/1.24
N=55800/124
N=13950/31
N=450
Answer = 450 students Last Year
good day
Verify:
Last year 450
This year 450*1.24=558 okay
