Ivahew [28]

Answer: Children tickets cost 7.50

Adult tickets cost 12.50

Step-by-step explanation:

Let a represent adult tickets

Let c represent child tickets

On the first day she sells 6 adult tickets and 5 children tickets for total of 112.50. This can be written as:

6a + 5c = 112.50 ...... equation i

On the second day she sells 8 adult tickets and 4 children tickets for the total 130. This can be written as:

8a + 4c = 130 ....... equation ii

6a + 5c = 112.50 ...... equation i

8a + 4c = 130 ....... equation ii

Multiply equation i by 4

Multiply equation ii by 5

24a + 20c = 450 ........ equation iii

40a + 20c = 650 ......... equation iv

Subtract iii from iv

16a = 200

a = 200/16

a = 12.50

Adult tickets cost 12.50

From equation ii,

8a + 4c = 130

8(12.50) + 4c = 130

100 + 4c = 130

4c = 130 - 100

4c = 30

c = 30/4

c = 7.50

Children tickets cost 7.50

The bird population in Louisiana is decreasing at a rate of 15% per day due to the oil spill. If there are 12,000 birds today, h
tiny-mole [99]
<h3>Answer: 395 birds</h3>

==============================================

Work Shown:

The formula to use is

A = P*(1+r)^x

where,

P = 12000 is the initial population

r = -0.15 represents the growth rate in decimal form; which is really a decay/decrease due to r being negative

x = 21 days have passed by (3 weeks = 3*7 = 21 days)

These values lead to...

A = P*(1+r)^x

A = 12000*(1+(-0.15))^21

A = 12000*(1-0.15)^21

A = 12000*(0.85)^21

A = 12000*0.03294560142183

A = 395.34721706196

A = 395
