65n ≥ 10,000 What's n?
don't know !
could u tell me how to start solving this question ?
Divide both sides of the inequality by 65
u mean 65 and 1oooo ?
yes divide 10000/65
it would come in point that is 153.846..........
right. since we don't want a remainder, (n has to be an integer) take the n to be 154. So the smallest 5 digit number will be 65 * 154
this means rounding up of the number ?
yes. 153.846... * 65 = 10000 exactly, so you have to round up to 154 to get an integer
in each case , can we apply this method ?
thank uuuuuuuuuuuuuuuuu so much :) !
