Answer:

9 kids tickets

Step-by-step explanation:

Let k = no. of kid's tickets

12 - k = no. of adult's tickets

9.50(12 - k) + 6.50k = 87

95(12 - k + 65k = 870

1140- 95k + 65k = 870

- 30k = -270

k = 9 kids

Answer:

P(t)  =  27000 - 4*t

Step-by-step explanation:

Over a period of time, if we know the  population at certain time,  and the rate of change of the population, we can express the function describing such population by means of these two parameters  

Then:

P(t)  = P₀ + 4*t

In our case

P(t)  =  27000 - 4*t

Sign minus is for decreasing population t is in months, 4 is the rate of change and finally 27000 was population the first time Talulah counted the population

n200080 [17]
Hi there!

To find an equivalent function for this function, we can just simplify it. 

f(x) = (6)4x

f(x) = 24x
is an equivalent function. 

Hope this helps!

Answer:

Read explanation

Step-by-step explanation:

Wow I'd love to go to that store of yours! :P Anyways if you were asking for the new discounted price I solved this equation: 12*0.8 and got $9.60. But if it was asking for <em>how </em> <em>much </em>was discounted, I would do 12*0.2 and $2.40.
