The table below shows the the total amount of money a desposited into the account after. A certain number of months t since opening it which equation models the relationship between a and t ?

A) a=250t.

B) a=500t

C) a= 250t+500

D) a=500t+250

Answer 1

The answer would be D) a=500t+250. This is because she initially opened the account by depositing an amount of 500 dollars. And after that she deposited the same amount of money each month.

Then I did this:

500+250= 750

Then i added in the other 2 months

750+250+250 = 1,500 which is the first value on the chart.

Answer 2

C

Explanation:

At 4 months, Ms.Gibson has $1,500 deposited.

lets run that through each choice:

A)

250*4=1000

so A is no.

B)

500*4=2000

So B is no

C)

250*4=1000

1000+500=1500

So far, C is correct!!

D)

500*4=2000

2000+250=2250

So D is no

From that, we can conclude that C is the correct equation
