So, after one year will will have the new population of 23 000 * (100 %+2%)
(the 100 % is the old population and the 2% is the increase), that is:
23000*1.02=23460
(102 % can be represented as 1.02)
And for the next years, we have to repeat the procedure.
a more generic rule would be:
y=23000*
(x is the number of years passed)
7/3 × 2/5
= 14/15
anything to ask please pm me
Answer: The director can choose two singers from the 20 singers in 190 different ways.
Step-by-step explanation:

So the number of ways can the director choose two singers from the 20 singers=
Therefore , the director can choose two singers from the 20 singers in 190 different ways.
I believe that x=9. I used cross multiplication. First, I multiplied 6 by 15. Second, I divided this product of 90 by 10. The quotient is 9.
