If at 10 Am there were
10 AM.......................12 people
11 AM........................27 people
we see that in an hour the number of people increased by
27-12=15
1 percent of 12 is
12/100=0.12
15/.12=125
the increase was 125%
No because x=4 and y=-5 and when you plug it in you get 5(4)+2(-5)=8 20+-10=8 and 10= does not work so it is not a possible solution.
