Answer:
Adult tickets=275
Step-by-step explanation:
form 2 equations from the given info.
x+y=611
y=x+61
x being the adults and y being the students tickets
then substitute the y equation into the first equation.
x+x+61=611
2x+61=611
2x=550
x=275
and you can check by putting 275 back into the original equations :)
The colony doubles every hour, the population is equal to
p = 2^t
<span>Where t </span><span>is the time in hours.</span>
We are able to see this because:
2^0 = 1
2^1 = 2
2^2 = 4
Notice that the x coordinate of the graph corresponds to the time, and the y coordinate corresponds to the population.
<span>Thus at t = 9
</span>p = 2^t
p = 2^9
p = 512.
The correct answer is 512.
