Answer:
1464 Students
Step-by-step explanation:
10% increase of 1000 = 1100 year 1
10% increase of 1100 = 1210 year 2
10% increase of 1210 = 1331 year 3
10% increase of 1331 = 1464 year 4
79
60<xy<100
y -2 =x
if it is prime
y cannot be even
so y could be 1,3,5,7,9
x would then be 9,1,3,5,7
but to be between 60 and 100
x must be 7 or 9
so the number must be 79 or 57
57 is not prime so
the number is 79
5x/12 - y/10 +9
