The population of a culture of cells grows according to the function P(t)= 90t/ t + 1, where t> or =0 is measured in weeks. C
butalik [34]

Answer:

The average rate of change is \frac{18}{5}

Step-by-step explanation:

Given function that shows the population of a culture of cells,

P(t)=\frac{90t}{t+1}------(1)

Where, t represents the number of weeks.

Thus, the average rate of change in the population over the interval [0,24],

m=\frac{P(24)-P(0)}{24-0}

From equation (1),

=\frac{\frac{90\times 24}{24+1}-\frac{90\times 0}{0+1}}{24}

=\frac{\frac{2160}{25}-\frac{0+1}{0}}{24}

=\frac{2160}{25\times 24}

=\frac{2160}{600}

=\frac{18}{5}

irina1246 [14]

Answer:

Step-by-step explanation:

If student ticket = 215 then 215 x 3 = 645$

Remaining tickets = 522 - 215 = 307

So adult tickets = 307 x 4 = 1228$

Total amount = 1228 + 645 = $1873
