Percent increase=increase/original times 100
increase=26-21=5
original=21
so
5/21 times 100=0.23809523809523809523809523809524 times 100=23.809523809523809523809523809524
round
24%
so 24% increase
48000=55210(1-0.0109)^t
Solve for t
t=12.77 =13 years
2010+13=2023
So the answer is c
4/5 divided by 1/10 is 8 the answer is 8
