Answer:

money owed (in order): $850, $870.40, $891.29, $912.68

Step-by-step explanation:

The formula is

money owed = amount owed the previous week + amount owed previous week × interest rate (in decimal form)

so thats:

money owed = amount owed the previous week + amount owed previous week × 0.024

we can simplify that to:

money owed = amount owed the previous week x (1.024)

after 0 weeks:

$850 (just started, no interest added)

after 1 week:

$870.40

after 2 weeks:

$891.29

after 3 weeks:

$912.68

A farmer was counting his chickens and pigs. He had 16 animals in all and counted 54 legs. How many chickens does he have
Vikentia [17]

Answer:

5 chickens

Step-by-step explanation:

Let's set chickens and pigs with variables "c" and "p" respectively.

We know there a 16 animals in all, so there are:

c+p=16

We know there are 54 legs and chickens have 2 legs and pigs have 4 legs each:

2c+4p=54

Now we have our system of equations:

c+p=16

2c+4p=54

We are trying to find the number of chickens, so we write the first equation in respect to c.

p=16-c

Substituting the first derived equation to equation two:

2c+64-4c=54

Simplifying:

64-2c=54

2c=10

c=5

So there are 5 chickens.

blsea [12.9K]

Answer:

He can purchase 300 white baloons.

Step-by-step explanation:

150$ is 15000 cents

15000 = 60b + 30w

b being number of blue baloons,w number of white baloons and 60 and 30 prices in cents

15000 = 60*100 + 30w

15000 - 60*100 = 30w

15000- 6000 = 30w

30w = 9000

w =300

number of white baloons is 300
