30%
percent means parts out of 100 so 30%=30/100=3/10

42 is 3/10 of x
'of' can be translated to multiply
42=3/10 times x
multiply both sides by 10/3 to get rid of fraction
420/3=x
140=x

the number is 140

We set up the equation 4000*1.05^t>10000.  Dividing by 4000, we seek to find t such that 1.05^5>2.5.  A calculator gives t>18.78, however, since interest is compounded yearly, we want a whole number of years.  The smallest whole number greater than 18.78 is 19.
