in 1980 it was about 20%
in 1990 it was about 30%
about a 10% increase
in 2000 it was just under 40% so almost a 10% increase
so for estimating you can say it is increasing by about 10% every 10 years
so in 2010 you can estimate about 50% are unmarried
The least number of pens each boy can have brought is 60
<h3>How to determine the least number of pen?</h3>
We have:
Vincent = 6 packs
Aidan = 20 boxes
Factorize 6 and 20
6 = 1 * 2 * 3
20 = 1 * 2 * 2 * 5
Multiply all factors
LCM = 1 * 2 * 2 * 3 * 5
Evaluate the product
LCM = 60
Hence, the least number of pens each boy can have brought is 60

The correct option is C. In Nuclear reactions, two nuclear particles collide to produce products that are different from the reactants. During nuclear reaction, a lot of processes take place. In nuclear reactions, the total energy is conserved. Thus, the missing rest mass energy can be accounted for by using the Einstein's formular to find mass - energy equivalence.
